Advice please?

So I have been ttc for 6 months now and have PCOS I’m on medication and I’ve just started ovulating (I think). Anyway my friend started trying way after me and got pregnant on the second try… she’s now 10 weeks but has been horribly sick on the verge of hyperemesis which I understand as I had it with my first (we are both ttc our second children) but there’s only so much support I can give when I’m struggling with ttc my second. I’ve been great and reassuring and supportive but I feel crack starting to emerge, my jealousy coming through, the old “at least you’re pregnant” thoughts getting closer and closer to coming out.

Any advice if I should say anything or how to take it all in? I can’t keep hearing about how miserable she is when I want that misery (easy to say when you’re not in the situation though).

TIA
