C section fears

I had a c section 6 days ago. I feel like I’m recovering quite well. I’m able to get up and about much better. The pain gets better every day and yesterday I went for a walk and it was hard but I managed it. I’m just so anxious and scared. I’m frightened to death that at any moment my internal or external wound will bust open and I’ll get internal bleeding and die. It sounds silly but I’m terrified. I do t actually have any symptoms to make me think this. It’s just stuck in my head. Are these complications rare?? Had it happened to anyone? I’m also scared to death that something bad is going to happen to me. My anxiety is through the roof. Does anybody have any reassuring words? Just to kind of reason with me. Any kind words appreciated.
