I was exactly the same as you with mine as I didn’t realise my body was addicted… the feelings you’re having are completely normal. I went cold turkey with mine and this is exactly how I felt I went to see the GP as I have really bad health anxiety anyway and they confirmed it. After cold turkey those symptoms usually last around a week and then it’s more of a mental battle.
I’m at 3 weeks today after cold turkey and I do feel like a completely different person but I will say that if you’ve suffered with anxiety/depression before then it will rear its ugly head, it definitely gets easier and better by the day and you can definitely function and feel like a normal person but especially as a woman I’ve found it really hard this week with my hormones being all over the place. If you find you’re struggling with the panic/anxiety side of it I’d definitely speak to the GP, you’d be surprised how much they deal with this!
They gave me a mild anxiety tablet on top of the ones I already take to help with the panic/anxiety and I’m getting reviewed regularly now and getting the help I need.
If you haven’t suffered with mental health before this side of it all may be easier for you, but don’t be surprised if you wake up with feelings of anxiety/dread it is completely normal!
I’ll keep checking back as I know how hard it is at the early stages of your journey, I’m here to talk x
