Hiya Mugs :)
I find that before I have something really scary there are a few things I can do that really help. First challenging my thoughts about it really helps. Also, doing breathing and relaxation exercise to stay relaxed helps. So before I have to go I do my breathing and relaxation and I start off feeling much more relaxed. Also, exposure work helps me get there too. Finally visualizing myself getting through whatever it is really well also seems to help me get prepared mentally.
Sorry I could not be more helpful! Hope this helps a bit!
