Feeling guilty

Please don't bash me. I have two young babies to take care of. My husband works a full time job. I was working until I took maternity break and it's 3 months now after I delivered the younger one. I cannot afford day care. I have help from family. We have home mortgage that costs $1700 a month. I don't have a choice but going to work and I feel very guilty to leave my babies behind. I'm sure there are other moms in my position. How did you cope up with this? I am not sure if I'm slipping into separation anxiety. I don't sleep with these thoughts....
