How you deal with triggers?

I’ve been TTC since last December and it has been unsuccessful. The fact of me not getting pregnant didn’t help with my anxiety and depression and started gaining more weight. I had to pause TTC this month because I can’t find myself bringing a child to this world if I’m not mentally healthy, so I took this month to work on myself and it’s been good.

But a few days ago, I opened my social media and found that someone I was close to is pregnant. My heart shattered into pieces and couldn’t stop sobbing. A few people in my social circle have kids so I haven’t deal with this before. I was just crushed and later felt like shit because I shouldn’t feel like that just because someone’s pregnant but I can’t help it. The thing is that the girl deleted the picture right away (I’m guessing she’s in her first trimester and someone told her to not say anything until 12 weeks???) so why? Why did I have to open in the exact moment that I could see the picture and then it was gone? Ugh

So I want to know how you deal with these kinda things ladies. I know I’m still new in TTC but it hurts
