I see. I cannot help with that as confidence is the only thing in the world with which I never had a problem with. I can be a sociopath if I want to, completely disregard other's feelings. What I advise to do is first to get over the fact that you are weak, if you excuse me for the term. I advise you to go to a therapist. It does help. If you need to talk to smone, I will listen to you. Or read. You get it. You can get through this. As it seems like your main problem is that you break down easily. And i am very sorry to not be able to help with that, but I have never experienced what you are going through, so I cannot really give advice. (I went through other kinds of intense shitfuckery). Also sorry for bad English, 'tis my 3rd language.
