Sorry to quote the whole thing, but there's a few things I thought I'd mention/suggest. I know it'd be hard for you, but have you ever thought of joining the gym? If you wanted to put on a bit of muscle that is, and do your own research about nutrition/training. It's a hard thing to learn, getting to know your body is the hardest and how it responds to variations of exercise and diet. But surely, if this is something you think could (and would, I tell you now) increase your self esteem and self confidence, then it's worth looking in to? I mean I know it's not a miracle cure for your problems, but it's a real positive start and could trigger many good things as well as the increased confidence about yourself.
Ye but Im very depressed/tired at the moment and have very little motivation. I would even have problems in the gym. I would even be embarrassed e to work out in the gym. Its rediculous.
