I Can't Take Much More!! 😡😡😡

I've been having a nasal issue for the last year now but since I've been pregnant it's so much worse! It feels like allergies; congestion, clear watery mucus, congested face feeling, itchy eyes etc. But it's not and idk what to do anymore! I will be up at all hours of the night because I literally cannot breathe out my own nose but it's running like a faucet, and after a few hours it will pretty well go away but it doesn't stop for long enough to get a good nights sleep. I literally have tissue paper in my nose all day in order to keep my watery mucus from running down my face. I sneeze, and snot pours out of my face, my eyes itch and my face slightly swells. I've tried everything to get this to stop; opening the windows, dusting more, changing detergents, vics, purifiers, steaming, drinking more water, changing diet, medication and all is failing. If I were to count, it would be close to 37 sleepless (or at least interrupted) nights. Does anyone else know what I'm experiencing or have any helpful tips??? I'm ready to just cry and give up completely at this point
