I have done something very stupid and im really sorry that I also let myself go loose in here. I was very irritated and had a panic attack at the moment so thats what happened after something didn't go the reasonable way I wanted it to go. Im very sorry. I hurted myself to make up for what I did but all I felt after it was emptiness inside of me. So so sorry. I feel ashamed and won't act like this any more. I understand that not everyone accept this apology and I feel the same. Something so stupid shouldnt be accepted.
The only stupid things are self-hate and self-pity. Everyone makes mistakes and faces emotional troubles. Don't wallow in them. Put them behind you. Hating and pitying yourself will only lead to more of it; start changing by doing things you like and respect. When I was younger, I despised myself because that was easier than doing something I loved. That was true foolishness.
If something upsets you, don't take action immediately. Stand up, breath, take a walk, pet a dog, do anything to clear your head. Then do things you won't regret. It only seems hard until you get started.
Do this, and you aren't just forgiven by us; you will be able to forgive yourself.
