TTC with PCOS and depression

Nadine
So my husband and I have been TTC for over 2 years, I have been diagnosed with PCOS for most of that and recently with depression.
I am just wondering if anyone else has gone through this and how they coped with the constant disappointment of not being pregnant? I feel like I'm seriously struggling and it has been so long and nothing is getting better or seems to be working. 
Thanks 🙂
