(Trigger post) Venting

I had a miscarriage last year and of course I really want kids and would love to have then sometime but my partner tells me today the he wants to start trying and the thought of that kind of gave me anxiety because I keep going through the tough experiences last time I had a chemical pregnancy this yr and I have suffer from depression and anxiety PTSD and a few other things but I'm scared that now if I start actively trying will it happen I've already known that I wanted to eventually try again but not with so much pressure on it now I feel like it I don't get pregnant I will just feel more bad I'm really just nervous about the whole thing
