am bipolar depressed

I was wondering if I am Bipolar or Depressed?
I was wondering if I am depressed or bipolar. My friends have been complaining about me lately and asking if I was.
I took a quiz thing for depression and I have a lot of the symptoms. I stay in my room most the day. I don’t have much of an appitiet. I sleep WAY to much. I have mood swings. Sometimes I am sooo hyper and happy but then I am crying. I am really socially isolated. And a lot more that I can’t think of right now.
So am I? I haven’t done any research on Bipolar anything, so what is it? Thanks in advanced for your comments.
yes it sounds like you are bipolar you need to see a psychiatrist and get assessed then the appropriate medication and maybe some counceling
