Hi. I understand. I also have emotional highs and lows. Mine are for no apparent reason.

I have learned, from some very wise people on this forum, that fighting the lows (feeling frustrated, angry, disappointed in myself) does NOTHING to make them go away. It just adds additional garbage to the chaos that's already in your head.
So I try to relax and go with the flow. I mentally "check out" of the down times and just keep busy, go online, do whatever distracting things are around, without the thought or hope that they will CHANGE what I'm going through, but rather just to make the time go faster until I happen to feel better.

I hope that I have explained well, I have a little trouble with that.

Keep posting and keep venting and pm me if you feel like it.
