Pregnancy symptoms

Ok, I'm sure I sound crazy butttt:

I'll be 7 weeks tomorrow. I've had the worst all day sickness the last week. So miserable that I can't even function. My doctor has me taking ginger root capsules, vitamin b6, and unisom to help with nausea until my bonjesta prescription comes in.

Yesterday, my nausea slacked up. Today, I've been able to eat, shower, and some what function with only slight nausea.

I know I sound like an idiot for worrying (because I'm sure it's just my medicine kicking in) but should I be worried that symptoms have gone away this quickly? Everytime my symptoms slack up even the least bit, I always freak out thinking I've had a miscarriage. I just have really bad depression and anxiety, and since I found out I've constantly felt like this was too good to be true. So this pregnancy has been hard on me because I constantly fear for the worst. 🤦🏼‍♀️
