First of all, that is too cute! Do it, she will love it!
You need to do what feels right
I suffered with anxiety and depression for years until I met my current boyfriend, we've been together for 3 years now and its amazing, and it doesn't get in the way, it makes it better
.
At the end of the day, its up to you. Do what feels right, if its the right time to tell her you have true feelings for her then tell her, maybe you'll get an amazing reply or not. You need to be ready for it, and need to accept what goes with it. She will either say she isn't ready or that she loves you. Maybe talk to her, take her somewhere nice and tell her that you think your in love with her, see what happens
If you truly believe that your relationship is ready for it, do it! My boyfriend told me he loved me after a month or so, 3 years later he's still making me love him!
Good luck with whatever you decide to do, just do what feels right!
