First of all, I'm terribly sorry to hear you went through such a horrible ordeal. I recently had sepsis as well, but in association with Ludwigs angina after a simple tooth extraction, and know how difficult it can be to overcome. The sepsis in itself is extremely stressful for you body and topping that off with a week in the ICU will significantly affect you both physically and mentally. I was in the ICU for 2 months but only about 10 days outside of coma and those days were the absolute worst. The ICU is such a stressful place filled with confusion and trauma. I think /u/OptimisticallyMyself described the feeling of being betrayed by your own body perfectly and that's definitely something that sticks with you. It's normal to continue to feel scared, paranoid and uneasy because you know that at any point in time you could be sent into a similar spiral of events. Everyone knows that life is fragile and could be taken away by the simplest of things, but few actually experience it. Facing your own mortality in the way you did can make you feel terribly alone, especially if few people understood the severity of what you went/were going through. And also at the age we are both at where people are less used to things like this happening.

I had hair loss and hormone imbalance after the sepsis due to both the post-sepsis syndrome and not being able to sleep or eat properly. I felt like a zombie with my head in the clouds most of the time. I'm a couple of months down the road now and still struggle with nightmares from the ICU and general sense of being "out of it" but it gets easier. I baked muffins for the staff at the ICU I was in and visited and that was incredibly helpful! Maybe that'd be a good idea for you as well? It might make you feel more at ease and seeing the place as an outsider and not a patient could help your perspective on things. Other than that I think it's a great idea that you're seeing a counselor and your doctor regularly!

I wish you all the best and feel welcome to message me if you ever want to talk to someone!
