No problem there, I know those sort of things are difficult. Well life in question is indeed difficult...
I am actually almost 21, between high school and profesionnal studies and I know I'm sort of trapped since I'm like 18 to go on because I don't feel like continuing and the fact people do sometimes reject me and my difficulties, but I think the best to me would be to focus in school (partially) more instead of working and being tired after that, I know my parents can support me in this instead because too much makes me pressured.
And due too the harsh feelings I'm getting at times, sleep is helping me a lot to feel better, because I know what's going on if I don't, so it's basically this which makes me want to sleep most of the time, it's something which calm me down.
