Feeling hopeless

I've had 10 miscarriages in total. As if that isn't bad enough, I get hyperemesis gravidarum during my pregnancies so I get really sick and often hospitalised for it.
Just having a down day. In my 2 week wait and my thoughts are ranging from "I'll probably never get another bfp" to "I'll get a positive but miscarry again" and then to "even if I don't miscarry I'm gonna be so sick and nobody will understand."
Does anybody else feel completely hopeless at times? CD21 and due on CD28 and done nothing but cry and moan for the past 2 days 🙈
