Feeling down

So my boyfriend and I have been trying to get pregnant since October of 2019 and it’s just not happening. So after a semen analysis we find out the only way we can get pregnant is through ivf. Financially it’s not a good time but medically it feels like it has to be now because I have multiple sclerosis(ms) and can’t keep delaying taking my meds to keep myself from getting any worse and slow the progression. Idk what to do and feel so defeated right now
