Is it possible that all ive been through has made me bipolar?

I once was a normal kid, but between my home life (dad yelling about every little thing possible, mom nagging about how messy the house is, when its not messy at all, and oldest brother being abusive towards the whole family, using and abusing us and robbing us blind for drugs), and trouble at school (there was always trouble at school, be it people picking on me, trying to start a fight with me, or teachers that just plain hated me), I was having mental problems before I got out of high school. For a while I was struggling with depression, anxiety, mood swings (almost every day I felt miserable between being depressed/anxious or going between depression and manic spells (the manic spells would usually last between a few minutes to a few days and were just as bad as my depressed spells (at times i kept going between depressed and really happy and i felt like i was losing my mind) that lasted between a few weeks and a month) and cutting. Now I think I might be stable, but I can't truly be sure as I haven't even had my seroquel xr (which is to stabilize my moods) dose increased (it was doubled from 150 mg to 300 mg) for a week yet and the reason it was doubled is for my depression (which i take 30 mg celexa for). I think I might be bipolar, though I haven't been given a diagnosis, I guess my psychiatrist just wants to treat the symptoms and not label me. Is it possible that all I've been through has played a part in me starting to have mental issues? Or was it just a random occurrence that I came through with mental issues?
