Keep showing up here and sharing ideas. Keep praying and trusting God. Lots of people are praying for you! 

Every single person has some cross to bear, whether it be health problems, financial problems(from grinding poverty to significant debt), loneliness(both single people and those in loveless marriages), difficult and mind numbing jobs, 
persecutions for their faith, etc. etc.
Whenever I am tempted to throw a pity party for myself I think about those little kids on those St. Jude's Children's Hospital commercials. Babies and toddlers with cancer having to endure all those gruesome tests, surgeries, chemo treatments or, kids without limbs, born blind, having to deal with cerebral palsy. Then there is the anguish of the parents. 
...and I feel ashamed of myself for complaining about anything because my worst day would be their best day.
So, lack of gratitude for the good things God has bestowed upon you is surely the quickest path to despair and sin. 

This is just getting depressingly bad. I wish I could even think of something interesting to go do by myself.

A road trip to a week or two stay at some religious congregation sounds interesting.

I'd swing by if it wasn't over $650 round trip in gas and oil change for the car. I'm not a fan of flying. Maybe if Trump gets elected.

I was just skimming an article that talked about the beneficial effects -- contra depression -- of just getting outside in nature. I was quick to believe it. That's why I insisted on living in a rural area. It really does help. It's a real break to get outside and reset everything. Moving your body in light exercise (walking or better) multiplies the effect.

Try those things.

In the summer, I do a lot of outdoor stuff. It's too cold and gets dark too early in the winter. 

With all the weirdos around, you should be thanking God that you don't have to deal with them.  Read a good book, listen to beautiful music, thank God that you're healthy, exercise either outside or indoors, write to a friend or relative or better yet - call them. Go to a concert, a movie, go to a park & people watch.  You might then be grateful you don't have to deal with all the nit-wits. Do volunteer work.  Guaranteed if you do these things you will soon be glad to have alone time & not complain.  It's your own fault if you feel lonely with so many things to do - & needs someone to do them.

Please post again next month after doing some of these things. I'd like to know what - if anything - helped.  I'm serious. 

This is what's really hard for me. Due to my autism (high functioning) it's really hard to come up with things to do that I don't find inherently interesting on their own, especially things I can do by myself. Board gaming is a huge interest, hobby and passion of mine, for example, but it's not something I can go do by myself. I do read books and listen to music at my house as well as play some video games. I'm not a huge fan of concerts. My home speaker system can reproduce sound much better than the speaker system at a hall or theater so music sounds better at home and since I'm not going to meet the performers anyway, paying to go listen to music that will sound inferior doesn't seem like a good idea. I do like movies and go to them occasionally, however, in recent years, most movies are trash and I wouldn't want to pay to see them as a matter of principle. 

When the weather is nicer, I do go to parks and places to walk my dogs, but in the winter, it's generally too cold and dark too early to do this. Not super interested in people watching, but I do like to get out. I do go out to dinner on occasion as well. The problem for me is that in order to make friends, I need to be able to repeatedly interact with them to get to know them before anything else. It's hard to explain, but I pretty much need to be able to learn about them, learn what common interests we have in order to learn if they're someone I want to engage with further.

We're a month past the equinox already and gaining minutes of brightness steadily. Scandinavian expression: There's no such thing as bad weather, only bad clothing. Lots of recreational websites explain how to dress to stay both warm and comfortable. Unless it's seriously bad (as in thunder-blizzard), try to bundle up and get outside daily, ideally between noon and 2 PM, for longer than it takes just to walk the dogs. Throw snowballs at a tree or a boulder or a solid brick wall. Try identifying deciduous trees only by their bark, learn about how cloud formations predict the weather, observe what the squirrels and birds and other critters are doing at those times when you're out quietly on your own.

As for people, make friends with the Saints. There are a lot of traditional websites that detail their histories, some of these sites follow the daily liturgical calendar. Saints have had experiences that make the most valiant of us seem like wimps; we have a lot to learn and admire in them.

All of this is a matter of deciding that you want to take these simple steps every day. Ask Our Lord for encouragement and guidance. Look to Him and He will send you what you need.

Don't allow the seasons to be a deterrent, or maybe someday you can move to a warm climate.  Winter walks can be brisk and refreshing, as well as walks in gentle rain.  As I worked outside with cattle I never took up winter sports (I worked in the snow and cold, I don't need to go play in it), but many find winter activities as fun as summer ones.  There are great clothing, camping, and other gear options for winter.  I live in eastern WA and looked up sunrise and sunset here for December 20 (shortest daylight of the year) and there was still a solid 8 hours + of daylight.
