Hi Andrea,
I'm sorry you are having such a bad time of it now. I do understand. I have spent a lot of time telling myself that I'm not worth much and a bother.
Sometimes hearing about people that care doesn't do anything for me either, but I have learned to call on them when I need them. I try to be there for them, spometimes not so good at that.
If your therapist trusts you to do the right thing...do you trust your therapist?
Here's a bunch of

s. I know it isn't much but sometimes it does help.
Hope you are feeling better soon and maybe can reach out to those you know care about you.
