Feeling disappointed in myself 😔

So I always envisioned myself being the most active healthy pregnant person ever.... Fast forward to me at 7 weeks and I am so tired and sick I can't do ANYTHING much less work out, and all the healthy foods I used to love are making me gag.... All I can eat are carbs and complete and utter crap😳 generally speaking I'm the kind of person who has to work out all the time 1. For my sanity and 2. To maintain a normal figure... Sooooo scared of blowing up!! My Dr told me I'd start to feel better come second trimester but I'm worried I'm doing too much damage now. Anyone else feel disappointed by your expectations vs reality!?! Also even if I had the energy to work out I'm now deathly afraid of the gym and all the germs 😷
