A dr can't give you resilience, I really wish it were available in pill form, so I myself can take some PRN, but sadly that's not an option. And resilience is exactly what you need.

You say your therapist doesn't take you seriously, doesn't seem like you take yourself seriously either.

Since your very first post here WRT your "I do nothing" issue, what steps have YOU taken to change that?

Sure its not always nice to go out alone, some days the idea itself sucks, but as you've pointed out numerous times yourself, nothing except you is actually stopping you.

Going out alone cannot physically kill you, and you have to go somewhere because people are not going to line up outside your bedroom door wanting to make friends. That's not how life works.

No. Unfortunately you're going to have to bite the bullet and do that which you loathe, if you are to have any hope of rectifying this situation. And for that dear jelly, you're going to need a shytload of resilience.
