Bishop Sanborn has an excellent sermon on the Catholic teaching of predestination. He makes it clear that all of the souls in heaven were predestined and elected by God without any consideration of foreseen merits. He says it is impossible to enter heaven unless a soul has been predestined for glory. He explicitly mentions Romans ix., 15 "I will have mercy on whom I will have mercy, and I will shew mercy to whom I will shew mercy."

Of course no souls are actively predestined for hell, but to say that a soul can enter heaven without being elected is Pelagianism.

If every soul in Heaven was predestined for it, then logically every soul in Hell must have been predestined for it. 
I'll watch the video this evening to see how Bp. Sanborn explains it but as it stands that sounds like a direct contradiction of the Church's teaching(i.e that double or negative predestination is false).

I read a passage in the Bible where it states if you repent of your ways and turn back to your own ways, there will be no more forgiveness left for you from heaven.

Can't tell you how many times I've been back and forth with my faith.
I guess st john vianney talks about the sins God no longer continues to pardon

How do i escape this despair? I feel like there's no hope. Lived most of my life with the way of the world... My own stupid fault

I can’t tell you how many times I’ve fallen.... 
I was 17 when I pretty much committed the (at the time) the biggest sin of my life of my to feel I had fallen so far from Gods grace He wouldn’t even try to reach for me. That type of thinking led me down a path of terrible, painful choices I carry on my heart, and will Probably never stop bringing up in confession. It was only once I found out I was carrying my first Child that I was jolted by a God that I couldn’t live for myself anymore, but I had to care for the soul of my child. It was not easy... I had a few months back, before I was pregnant, gone to confession to lay everything at Christ feet. It just felt like I didn’t deserve His forgiveness. That type of thinking brought me back into a life where I looked for healing in all the wrong places. It was a hard path back to God, but slowly I made my way to the foot of the cross, and once I laid everything down in front of Him... I asked Christ to help me carry the burden... because that’s what he wants to do...
Despair of Gods mercy comes straight from Satan. He wants you to believe that you can never reach God again because you’ve sinned to much. The only sinner that can’t be saved it the one who isn’t sorry for his sins. If you feel like you need to repeat confess sins, do it. There is no harm in it because we want to show God our humility before Him saying “I hurt you, I betrayed you. I’m sorry....”. 
Christ wants to carry your sins, all you need to do is lay them at His feet, and he will take your hand to lead you to Heaven.
