You know mental illness is like buy one get five free. I've got like 2 that are diagnosed and then 2 that haven't been, mostly because I'm avoiding getting an official diagnosis on them. Honestly I don't know if having a lot is normal of not. But if it's what you know then it's normal for you. It's not a flaw on your part so you shouldn't have to feel like it is or in anyway ashamed. Personally I think one is too many. Because dealing with even just one is a pain, so dealing with many is a skill all on it's own. Yeah sometimes I feel like a collection of symptoms more than a human being. I suck at this...But I guess what I mean to say is that your illness or in this case illnesses don't have to define you. So whether you have 1 or 10 you're still a worthwhile person.
