Depression and breathing?

So for the past few days I haven’t gotten out of breath. Held my breath.. nothing. Sprinted and held my breath.. didn’t even have a breathing increase. I just moved back to Georgia from California and left my boyfriend of two years there. (We’re still together). Left my car, cat, everything. I’m constantly anxious and stressed but most of all now worried that I can’t feel like I need to breathe. Could this be my depression? I’m 19 and parents have taken full control again. They take my phone at night, turn off internet, and lock all the doors. Keep in mind I pay my own phone bill and buy my own food.
