Out of curiosity, which meds did you try?
I did stimulants for years and they really distorted my sense of self in a way that was hard to put a finger on until I got out of the long-term traumatic situation I was in. I felt like life was a treadmill and I was looking at my feet the whole time — I could go really fast but I lost sight of everything around me. I switched to atomoxetine and while it still takes effort to start something, it’s much easier for me to take a task to completion (or at least further towards completion).
Different people have different reactions. This is not medial advice. Consult your physician to see if sertraline is right for you.
