I'm so sorry for what you're going through. I know at your age it's so hard to go through all this. Know this though, that you will get through this hard time and your life is not doomed because you have mental illness.

Sounds like you're not sure if you have bipolar or if this might be a situational thing. If it is bipolar it does usually just pop up in late teens or early twenties. Just my personal feeling, but from my experience personally and with family, stress has a part in it, but if you have bipolar it comes on and it would have come on no matter what. But that is totally just personal opinion.

Hang in there. I have experienced depression where every second was like torture and it went like that for months, but I just kept going and one day it got better. I've had a rocky life but a good one too. Take care. Hugs!
