Pregnant cheer coach.

Alright y'all. This might be long but I need advice. 😩😩

So I'm a cheer coach for a little league team. We have 1 huge competition in November and football games every weekend until like mid October. I'm the head coach in charge for 8-10 year olds. Last year there was 3 coaches & it worked AMAZING. This year it's me & my best friend and she has work at night so it's me 80% of the time. Now being pregnant has made life so extremely difficult. I'm 14 weeks & still getting sick & blinding migraines & anxiety through the roof. So now I'm stuck coaching a squad all alone. I have nothing planned , none of them listen and I could cry today. I want to quit SO bad because I know in the long run I'll be WAY less stressed out and more chill or even if another head coach could take over and I'll assist. Now my question is would you quit ? I've talked to the unit director 1027 times. He doesn't answer my calls or texts and tells me to "keep pushing" 😡 like I said I just feel SO overwhelmed & today was the first day of practice and I already wanna slowly shrivel up and die. Also adding in this is my 4th year & ive never felt like this

Edited to add*** if you were to quit how would you go about it?
