Dealing with Chronic Pain, Depression, and Fatigue

I'm having a hard time dealing with the chronic pain, depression and fatigue. I got real sick in January and was in the hospital with sepsis and a drain. After getting the drain out I went back to work like the next day...than caught Covid and managed to work through it. I worked with patients that had it as well. It's like I haven't recovered and am exhausted all the time. Im feeling frustrated with myself and am sick and tired of being sick and tired. I'm to the point I just don't know what to do....
