I am in of need of s9me positibe advice

I miscarried at 5 weeks, the doctor said the baby had deformities and chromosones split too many times. I've only been with my current Boyfriend for 7 1/2 months. He wants to try again, but i have anxiety about it. it was my first miscarriage and i don't want to have another one and I'm really anxious about it. I'm still depressed. idk i tried to talk to him about it, but he doesn't really understand.
