How to cope with TTC depression?

We have been trying for about 19 cycles now, recently everyone around me including close family members have announced they’re pregnant unexpectedly. I feel like my depression and stress is causing me not to fall pregnant but I don’t know how to stop feeling this way. I’ve been having regular acupuncture for the past 5 months but it doesn’t seem to cool my head at all. Can anyone suggest anything? Is it worth seeing if my doctor will prescribe anything? We are currently undergoing investigations as to why we can get pregnant but everything is coming back normal so as far as we know, everything is all good but even knowing this doesn’t seem to stop me stressing out 😢
