just Diagnosed with PCOS

Chez
I just went to a specially doctor, and she has diagnosed me with PCOS 😞 which explains why I haven't gotten pregnant yet within the last 2 years of ttc. Idk what to do or what to think. My husband on the other hand doesn't fully understand it.  He's saying it's okay and acting as if it's no big deal and that it's all cause I started to become "Lazy" . When honestly , I've just been so exhausted lately and don't feel like myself, which is also another reason why I made a dr apt to try and figure out what's going on ... not to mention I just started packing on a crazy amount of weight too. 
I don't know how to explain to him what's exactly going on , with out him just blowing it off or me getting more angry or sad by talking to him about it. 
Especially with myself still trynna wrap my own head around it.Â
