Depression

Sooo...I have been dealing with depression and anxiety for a long time now. But for some reason I just can’t shake it. I have heart problems. And my heart doctor said I would be able to have children, but i still have that big scare lingering around. I’ve had one miscarriage already. My fiancé has been so supportive with everything, but I still can’t seem to break depression. I’m so scared of everything. I’m scared I might have another miscarriage and that adds on to my depression. I start over thinking bout what if my child ends up having to go through what I did? Medical condition wise? That makes it 120X’s worse! Depression keeps sticking around. I can be happy for a little while and it just bites me in the butt. I start overthinking about everything. What if I push my fiancé away? What if I lose another child? What if they have heart problems also? What if I cant get pregnant again? It just goes on and on. I could really use some friends. I just need more support. I know my fiancé tries, but it still is so hard.
