Does anyone else have first trimester anxiety?

My anxiety is centred around the fear of nausea, feeling sick, being sick to my stomach, not being able to function due to extreme fatigue, food aversions and eating only crackers etc. I'm only 7 weeks and I'm extreeeemely bloated. I look like I'm 20 weeks at least. It's my second pregnancy and I think remembering what I went through the first time is making harder to not worry about it this second time. You'd think I'd feel prepared and better equipped but I'm fearing the worst (what I experienced in my first pregnancy). I'm wondering if anyone else is in a similar boat? How do you stay in the moment and not worry/fear? Thanks for listening!
