Baby/life rant

Anybody else feeling disappointed by seeing EVERYBODY but you get pregnant 😔 I have high tsh levels and I've been trying to get to see a doc now for awhile to confirm I have hypothyroidism and to be put on meds or if everything that's happening is just from stress. I currently have a daughter who's almost 3 and I left her abusive father earlier this year (we were engaged) and I met somebody (actually known 5 years ago) and he makes me feel so happy even though we have arguments about certain things. Idk if I'm overreacting about not being able to conceive or not and maybe I should just wait till marriage but knowing i can't get pregnant right now is making me feel more than incompetent and I feel like I have nobody to talk to anybody. I feel beyond alone in the world besides having my daughter.
