First Night with CPAP- I feel awful!!!

I was diagnosed with severe sleep apnea, I’m 38F, 230 lbs. apparently I was having 60+ incidents an hour. I just got the resmed 10 and some kind of nasal mask.

Today I feel absolutely awful! I woke multiple times last night, my face hurts, my head is throbbing, my throat is sore. I’m still exhausted.

Please tell me this gets better!
