Oh Smiley you are in a really bad place I'm so so sorry. It really sounds like you've got no support around you and that you're in a relationship which is not only not supportive but seems to be destructive to you. You know (you probably do but I'm going to say this anyway
) the LAST thing that's helpful is telling yourself you should be able to make yourself feel better - you feel bad and that's that, and the more you beat yourself up for not being able to think positively or psych yourself out of the bad feelings, the angrier at yourself you're going to get. Hell I do understand how it would be worth just about anything to get rid of feeling SO bad that even death seems preferable - who in their right mind WANTS to feel so overwhelmed? I really really want to emphasize though that feeling bad, weak, ashamed, out of control, helpless and at the end of the line - doesn't mean that YOU are those things.
It sounds too like you've had a lot of bad things happen in the past - trying to understand and resolve them is bound to topple you off your perch! But it also sounds like trying to deal with past stuff could be making things in the present intolerable. I know it's just words, but I want to tell you that you are NOT worthless! It's ok to FEEL that way, boy I could write a book on what it's like to believe you are worthless but that's an outside message - someone else has made you experience yourself that way. Would you be able to accept that you feel worthless, but that you AREN'T worthless? (Actually that's rich coming from me, who has the monopoly on equating feeling with being, but I hope you see what I'm getting at?)
Really what I'm trying to say is, please don't be ashamed of feeling so bad, you will have good reasons for it and maybe giving in to it a bit, rather than fighting all the time, will give you some relief.
Please keep posting Smiley - you've got support here!
