2nd misscarrage

I have had 2 miscarriages almost exactly a year apart. My first one I was 8 weeks and was bleeding and found out I lost it. I ended up in the hospital with clots the size of my fist, it ended in a D&C. I was super depressed cried all the time and felt lower then life. After almost a year I started to feel a little better. Then my husband and I got married and 3 weeks later I found out I was 3 weeks pregnant and a week later I lost that one too. I didn't get as upset with that one because I was expecting it. It's been about 5 months now and I'm getting depressed again and I'm losing my hair and feeling really down about myself. Wondering if I'm even able to have kids. Doctor can't find anything but progesterone is a little low. Feeling low, worthless and wondering if I'm good enough for my husband... Now I'm stuck in a rut and don't know how to get out and start feeling better about myself... Anyone have any advice? I sure could use it.
