Sorry some one stole your hat, that sucks. People in varying different environments can and will assume all sorts of different ranges of behavior for many different reasons.
It's also hard not to get upset when it feels others are not listening to you or understanding where you are coming from.
I'm personally quite bothered by people who think there is something wrong with cutting. I don't like the attitude, "I do bad things that I have no control over, please help me, there is something wrong with me."
I think we live in a society that is spreading the idea through out the world that we are not actually human beings capable of any sort of self control. That we are inanimate objects at the will of the wind.
If some one cuts themselves, drinks too much, ***** too much, smokes too much, etc... And feels they are powerless to control their behavior and wants to seek help, then such is their choice and that is fine. I find however, many people are quick to think that their view of the world and the way things work for them, is the way everyone views something or should view something. What's worse more is I'm guilty of the same thought process, but I realize this and work to correct it as often as I can.
There was a time in my life and such times may come again when cutting myself was and or is, the best option to relieving my anger and or sadness. I was always met with a series of options. 1: I could take my anger out on some one undeserving of it. 2: I could break something in a violent tantrum. 3: I could bleed it out and be done with it.
Most people will tell you not to cut yourself, that it is bad. This is a trite observation. There are many cultures where self-mutilation is viewed as art, a coming of age ceremony, and many other honorable things. It is no different than a tatoo. I've seen tatoos that are so bad it makes my scars look beautiful, lol. But tatoos, which were once actually quite taboo in some societies I imagine, are now much more acceptable.
If you cut yourself and that is the best possible way you know for you to deal with your emotions at any given time, I applaud you for your self control, I truly do. I don't recommend that any one cuts them selves, but I can say it's a much better alternative to what else is available to some people. And for those who are seeking attention, they usually find it, whether it's the kind of attention they want or not.
I don't really have any advice for you or much to say. Parties can be ****** or fun, I suppose it depends on the atmosphere and the people involved. Sucks you got your hat stolen by a ****** bag, lol. I mean really, who steals a hat?
Good luck to you on finding better social events more worthy of your time. Life is short, don't let it bother ya too much if you can.
