I've been there and trying, very carefully, to not go back there. My therapist is trying to help by trying to get to why I see myself the way I do. She believes it is distorted. She helps by bringing up things, such as my kids, and getting to the why of just about everything. When I realize that sometime's I don't even have a why for how I am feeling it kind of puts the kabash on the whole thing. She tries to get me to look through other people's eyes. Like my husband's. And actually believe them. Very difficult.
One of the reasons I put my picture out there was to get into my own skin and be comfortable...instead of feeling like a horrible beast. I have to say, it has truly been enlightening. Nothing horrible happened. The world didn't fall apart. I hated myself that much to think I shouldn't even be out in person. That was the shame I had. I say had, because I am getting through it. I've received support from people on here and even other's put themselves out there. I didn't feel so alone. That is what I needed. No one told me I wasn't hideous, and I wouldn't have believed them if they did. What I did feel was this amazing support system. And, like I said, the world didn't fall apart.
I wish I could tell you what else I've done to get pass that but it pretty much is just what I said. I had to pick something that scared me to death. I still can't say I believe people when they say nice things about me, my head saying they're just being nice, they don't know me, etc.. I can say, I'm not listening as much to the voice in my head that tells me I'm not likeable.
You do deserve to be liked by yourself. Doesn't mean you are vain. Just human.
