Worried about getting hooked

I just started lexapro and I feel much better. Things that were happening to me that I didn't even realize we're anxiety and depression are getting better. I've had this worry since starting however. The worry is that if one day I want to stop because let's say I start feeling emotionally blunted, and I try to stop but my anxiety comes back even worse and I feel so crappy I have to get back on but while I'm on I feel blunted. I just don't want to be stuck in a cycle like this forever and never be myself again Any experience with this or is this a reasonable worry? Thanks
