Gifs that dont post make me anxious. The one i used in this question wasnt the one i actually wanted, that one wouldnt post either. Freaked me out to no end. ;)
I use the breathing exercises I was taught in therapy to help handle my anxiety. With practice they almost become second nature; you just start doing them without thinking.
How should you handle anxiety attacks or how do I? First I text my ex and tell her off, then I go on Answermug and talk about it and then I eat a bunch of junk food, listen to music and then drink beer in my bathtub until I fall asleep. I usually feel better the next day. It's kind of a long self destructive process, but it works for me or you could meditate. Good luck. : )
