I'm pretty much truly alone. I'm 44 years old, no wife or family of my own. My dad and 2 siblings live 300 miles away so I don't get to interact with them very often. I don't really have any good friends. I have a few buddies that I'm able to do stuff with a couple of times a month, but that's it. They're all married and have kids so they don't have time to spend with me. Unless I need to go to the store or something, I'm pretty much home, by myself. Once summer gets here it'll be nice because at least I'll be able to go fishing after work and on weekends.
Another problem is that I'm a high functioning autistic person. Most people probably wouldn't notice anything odd about me once they get to know me, but it definitely makes this area of life very hard. It's extremely difficult to meet people as my social norms are backward. I need to already know someone before I want to talk to them. I usually do this by interacting with them in some kind of activity and I learn whether or not they're someone I want to know better which makes me want to talk to them and gives me something to talk to them about. If someone's a complete stranger, I have no idea what to talk to them about. For me, unless I'm talking to someone I already care about in some way, the purpose of talking is the exchange of information. If I don't know someone, I don't know if they know anything I need to ask them about, nor do I know if I know something I should inform them about which makes talking pointless.
I remember someone suggesting I should ask someone what kind of work they do as a conversation starter. For most people, this is probably a good opener, but the way my brain works, it's not. If this person is a stranger, why do I want to know where they work? How will that information be useful for anything in and of itself? Interrupting someone to ask them for a useless, meaningless bit of information is just . . . . . . . . I can't even describe how wrong and stressful that is. My church doesn't have any kind of social activities so there's no viable way for me to meet anyone.
Now if it's a person I know and care about in some way, it's completely different. I just need to find a way to get to know something about them before actually trying to converse with them.
Someone above mentioned prayer and while I do pray (probably not as often as I should), it doesn't help at all. If anything, it makes me feel worse as it will lead me to believe that God may help and when nothing changes or even gets worse, I obviously feel worse than before. Praying feels like calling someone you consider a friend who never answers their phone anymore. You leave them a voicemail and they never call you back.
Guess what? There's lots of people like you. I'm one. They may be 1 in 1000, I don't know, but that's still a lot of people with the same struggles. That personality type is at a huge disadvantage in this world unless they find the perfect fit for them.
Don't take this the wrong way, I'm always in a good mood and never intend to offend. Stop being selfish and miserable because you have no friends, practice charity and go be someone else's friend. Other people need friends too. Having such an outlook on life will really help you grow in holiness. Now here's the hard part, it may be hard to find people to be friends with, but if you have the resources to travel, I'm sure you can find people who could also really benefit from a friend. And, it would probably be easy in a way, because often times people who are lonely will happily talk away in front of new company for hours, so you won't have to talk much.
As for me, I don't have the resources to travel much for this purpose, and people I would be friendly towards don't want it, or are prevented by something (God or satan) for whatever reason. So my other option is to try to become as close of a friend with God as I can. I can't say that that is going anywhere near as well as it should, but I'm in a distracting environment, and hope to find somewhere better to go. It has helped me alot to get past the misery by just accepting the seemingly unfortunate circuмstances that I'll never fit in or have any friends on earth, and that's ok because were only travelers on earth. As for now, I'm trying to spend more time searching the depths of scripture, especially regarding charity. The 4 volume series "The Life of Jesus Christ and Biblical Revelations" from the visions of Anne Cathrine Emmerich have really helped me to better understand God and Jesus, even though it contains a lot of useless fluff and can't be considered anywhere near the same level as scripture.
And don't expect to feel anything from prayer. That is spiritual, we feel with physical things with the body. Just do your duty to God: loving Him above all things with your whole being, and always keeping yourself in His presence. If any feeling comes from it, that's probably either the freely given gift of consolation to an unprofitable servant, or a test of desolation to see if you will persevere in prayer, proving your worth and increasing your spiritual strength.
Maybe you could offer to buy breakfast or lunch for a few parishioners. That would be a conversation starter, and a means of getting to hang out with some company. They could probably make enough conversation among themselves that you wouldn't have to worry about what to talk about.
