Hun, calm down.
Most people on here have been through some amount of shit at some point in their lives. We may not know exactly what you've been through, and we're not disrespecting you for that, but on this forum, reactions like that are post arson.
You don't know what shit Forrest's been through himself. Leave it.
If that was to me, then I'll assure you that I do understand. It's really not a nice feeling [or lack of one I suppose].
However, it's not going to get sorted out by self harming or by a forum. You need to seek proper help, or at least a better coping method.
