Angry at myself

I get so fucking angry some times and this is something I have spoken about with therapists and been to anger management about and it doesn't work, even the therapists have said it doesn't work it's just there to make people feel better.

Anyway, some of the worst times I've felt angry is when I'm angry at myself, today for example I'm angry at myself because I saw someone doing something I've wanted to do for about 8 years but haven't got the confidence and such to do it, so I'm angry and frustrated and just AAARRGGH!!

I hate it, yes I'd rather be angry at myself than someone else but I tend to be self destructive when I'm angry at myself, the other problem is it doesn't motivate me, it makes me shut down.

I'm not sure why I'm writing this but it's done now so...
