Anxiety? Maybe idk.

I have a c section scheduled for May 11th and I had to have one with my son but it was emergency. I don’t know if maybe my anxiety is getting out of hand or depression but I keep getting a feeling like I’m not gonna make it through surgery and so I keep getting super guilty feeling and trying to spend every last minute I can with my son.. I can’t get the feeling to go away. I want to cry and I keep trying to explain to people that I can’t explain it and the most important person to me is my son and he’s all I want to be around because if I pass these are my last days with him.. people tell me to stop thinking negative but it’s just a constant thought.
