I've been told by my Psychiatric Nurse that I have SAD. But tbh I don't think I do. Yeah I depressed in Winter as does 99.9% of Scotland's population as sometimes our Winter is bad. Yeah I get manic in the Summer but wouldn't you if you hadn't seen proper daylight in months??? I told him I was depressed 2 years ago in the Summer. He said it was SAD. I was like but I'm always manic. He said it can go either way. I'm not officially diagnosed ie it's not on my file as a definite diagnosis I don't think. I can't take anti-depressants as I go manic so when I do get depressed be it proper full blown suicidal depression or seasonal depression I just have to ride it out. Which is really difficult. But I can't take meds for it so I just have to grin and bare it unfortunately.
