Any advice?

Sometimes idk what to do with all these things I feel. Emotions go up and down according to what I see and hear. People, events can make me laugh or cry in an instant. Movies, shows, songs, memories...all seem to affect me. (I suppose not ALL the time, but often.)

When it's good, it's really good; but when it's bad? It takes me down and sometimes it's hard to get back up.
