You're not alone, I used to feel the way you do constantly. and a lot of the time I still do.
I tried substance abuse to quiet my self loathing filled, always active mind. Failed epicly. Now I just icelate. Sitting at home caring for my kids and on the computer or watching TV.
It can get better though, I promise. Things have gotten somewhat better for me.
and if you think your therapist doesn't care about you, you need a new therapist cuz that's not right.
