9 weeks pregnant and my husband left me.

I'm 9 weeks pregnant and my husband just left me. I have been struggling with depression after some traumatic life events. Prior to finding out I was pregnant I started taking lexapro to help cope. I immediately stopped after finding out I was pregnant because of the serious affects the baby could suffer. Now I'm struggling ten times worse with my depression, pregnancy hormones aren't helping. My husband has been so unsupportive and now left me this weekend and is ignoring me completely. I'm devastated and can't stop crying. I feel like a part of me has died. I feel guilty because I'm scared this will affect the baby and I don't know what to do. I'm waiting for an appointment with my doctor.
