Im happy on and off..i am 19 and let what someone(including a parent) says get to me and bring me down. i just don't feel happy. i'm insecure and i overthink a lot.is this normal? ive been like this for years and i get anxiety when something upsets me and then i think about a bunch of other things that have upset me in the past and it just makes me feel worse,,i let it ruin my night..how can i get over this without seeing a psychologist?
