Hey ya'll, 
I'm posting this as a bit of a vent... my husband and I have been ttc for almost six years now... we both have children from previous marriages (I have a son, and he has 2 sons as well). It's begun to feel useless to continue trying, and I guess it has me falling into a depression (I already suffer from ad and bpd). I've tried every supplement I could afford, ovulation tests, tracking, planning, everything aside from fertility treatments because we can't afford them. Both of us have seen doctors who told us there's no reason we CANT get pregnant, yet here I am.. six years later, and still-- nothing. We had our children at young ages, way before any of our friends did, but now it seems like everyone I know is beginning to have children and I'm over here feeling like I'm dying inside because of our constant disappointment and failure to conceive... and as much as my husband is a wonderful man and an amazing father to our three boys, I feel as though he isn't serious about having a baby as I am, like I'm the only one who cares and he's just... there. 
 I'm not sure if I'm trying to ask for suggestions, advice or just looking for some support, but I'm sure I'm not the only one who feels this way... I feel completely vulnerable posting this, I'm a very private person and I don't even talk to my closest friends about any of this, as I fear the judgement of others, so please be easy on me...
