I am crying and I feel sad andworthless like nothing matters anymore but this happens all the time and then I go right back to being super happy and laught and sometimes I even get super hyper. I feel very guilty and I don’t know why and I have this constant anxiety in my chest. Sometimes these episodes, I’m not sure what to call them, can only last 2 hours or 2 days. I don’t know what is wrong with me.
