To me it sounds like you are going through a phase of depression that kept getting worse and worse. Now you are at the bottom of it and you can lift your head up. It only goes up from here so keep that in mind.
In your post you mentioned a lot of things that you can't and don't do anymore. If these are things that you know you enjoy and will make your life better then you have answered you question already.
Simply do these things that you haven't been doing. If you truly enjoy them and they will eventually make your life better. It will take some time and efforts on your part but that is all part of the game we call life.
You need to face these fears no matter how scary and fight until they disappear.
Everything you said in this post was negative, how about being a little more positive.
Maybe try talking to people, making a friend circle, being social, talking with confidence, maintaining eye contact and going out.
I understand that these things will be very hard for you. That is why I am suggesting a slow start into all of this. For example try going out once a week and take that as a big win! I know it is only once a week but from there you will gain so much and eventually gain your entire life back.
You just need to start, start somewhere and start small. Celebrate every victory no matter how small!
Now once you have got yourself a little confidence and the ball has started to roll. Now is the time to go out and try something completely new!
What is something that you have always wanted to do but have just never gotten around to doing it? Go out and do it! NOW!
