Depends on your reason(s), if you want to talk them out or tell me so I can give you better help, im always there for you.
What helps myself, is watching K-Dramas.. welp. Especially the extremely cliché, cute and dramatic ones!! True Beauty for example. It just makes me giggle the whole time and feel drawn to the scene. I forget the other stuff that goes throigh my head!! Try finding a sport you like. I go to dance classes regulary, they help me alot ((bc I am fully concentrated on dancing instead of my problems)). hope it helped a bit<33
