TTC for a year and a half now ...

It’s been a year an a half of trying for us now . Ugh I think I’m just going to give up and accept the fact that maybe we won’t ever have any kids together . I have one already but from a previous relationship . This really sucks I was hoping I could give my kid a sibling 😑 and everyone on my Facebook is pregnant and I’ve totally deleted them because it makes me jealous and upset ... idk what to do anymore
