Awwww Hope, unfortunately it is ‘normal’.
Take a look at my post here, only a couple of Topics down:
Don’t worry. You will improve, but unfortunately MAV is an incredibly rough ride and extremely testing like you’ve probably never been tested before.
Ugly relapses will occur whilst on medication. You will come out of every relapse though as good as you were before or better.
I have to tell you, though, the process of improvement can take years not weeks or months. Because of that, though, don’t get too downhearted by one relapse. You will be back to baseline very soon I’m sure. It’s incredibly frustrating though.
Sending you love 
from everyone here.
