Is this normal for PCOS?

Hi, I'm 16 and was diagnosed with PCOS when I was 14. I don't know if it's relevant, but I've only gotten my period once in my whole life. For the past 6 months or so, I've been feeling very weak all of the time, and I don't eat very much (maybe half a sandwich per day). I'm also tired all the time too, and I sleep for a good 9 or so hours every night. I'm not overly stressed, and I don't do much physical activity. Lately, I've bearly left my bed all day because I'm too tired and weak. Also, the other day I collapsed for no particular reason. I was just wondering if this is normal, or if I should go back to see my doctor. Any help would be greatly appreciated.

Go to a doctor and explain all this, no it does not sound normal.
