Got to get through this

It's now 7 months on from surgery and although physically feeling better I have been suffering emotionally. I am feeling much better than I did 10 weeks ago when I found my lowest ebb. However, I am now on medication ( Citalopram)for my anxiety and low mood. I have been to the doc's this week to have my dose put up to 30mg. If I can get through the surgery I can get through this. You will probably think me ungrateful, for everything I've been through why can't I be happy but I'm going to get better.
