How do you cope with the ttc pressures?

MissJelly
Seriously how does everyone do it, or am I the only one going completely batshit crazy right now???
​For the past 2 weeks, or slightly more, I've been crying all the time. I mean 20-30 times a day. Sometimes I'm set off by seeing a preg woman, newborn baby, people talking about it etc and sometimes I'm not sure why I'm crying!?!? We went away for a week and I cried everywhere!! It ruined our trip and made me hate it!!
​I know I've got a lot going on in the ttc space that's getting to me, but I can't seem to go with the flow like normal. We've been ttc for over 2 years now, although I know there's lots of people ttc way longer. We're waiting for test results and to book in <a href="https://glowing.com/glow-fertility-program">IVF</a> or <a href="https://glowing.com/glow-fertility-program">IUI</a> (what we do is dependent on the test results) - out apt is in May and that'll be a few months between apts. A very close friend got preg their first month ttc, and due to my own ttc issues I wasn't very supportive and told her not to get offended when I walk away when she's talking babies - but she MC a few days later. I know I didn't cause the MC, I can't help but feel guilty as hell!!! I've got endo, am 10 months post op but the pain is back with a vengeance 3 out of 4 weeks a month. To top it off I can't get away from preg woman and I know 5 people that are preg now and almost 10 that had babies in the last 3 months. Oh and I work with teenagers, 1 of who recently had a termination (not against them just ses like the universe is rubbing it in my face). Since my surgery 10 months ago my hormonal mood swings around AF have been off the charts, but they normally last a few days tops. Now I feel like I've had over 2 weeks of that. 
​Anyway, I'm feeling very depressed, I'm not eating properly and I don't want to do anything. I've had depression several times before and it's like it's back. How do you do it!?!?
​P.S. Please don't tell me to relax, as we  have tried this for almost 2 years with only a few months using OPK's etc.
