I’ve always had anxiety my whole life but a few months back I had really sharp chest pain and heart palpitations got an EKG and an Echogram, everything looked fine and was told it’s just anxiety which really didn’t shockme (i’m only 18 so anything heart related would be very rare) 
 
I got prescription for Prozac a few days ago but the first day I took it, it made me really numb for like a day and a half. My doctor told me to just keep taking it but I have been really hesitant to taking it ever since it made me numb. 
 
Is this normal? what should I do?
