single mom of two

someone tell me i can do this whole single mom of 2 thing. I got a divorce (he had an affair for a year), i was rocking being a single mom of a 2 year old. I was told i couldn’t get pregnant without IVF (my daughter was IVF), i’ve had multiple (5) losses, i tried for years with my ex. I got pregnant by my boyfriend of 6 months, i don’t know if i can stay with him. I feel like i’m failing at everything
