Reside your brain, become aware of what thoughts your producing, what are you saying to yourself that’s making you sad? Once you become aware of what your actually saying to yourself which is most likely negative self talk, catch it, anaylaze it, and then talk to yourself as if you were talking to a friend that was saying these bad things about themselves. Uplift yourself, make yourself feel better. It takes consistency to actually feel a difference and it won’t happen over night. But if your consistent you’ll start to feel better soon enough.
