Sorry to hear this.
To help out, it might be good to invite people to go places like the cinema, a lunch/dinner/drink somewhere. See if this works. But I understand overall how frustrating it can be to be actually trying to socialise. You'll get to where you want soon though, as long as you don't give up.
Where people and have come to your house, what activities do you do? And at the time how did you feel these encounters were going, both for yourself and the other person (ie what was the vibe you was getting from them?).
Regarding making friends in social clubs/activities, I do help in this area so feel free to send a PM if you'd like that help.
Wish you the best.
