Wow, I could have written your post myself!!! My depression makes it almost impossible for me to focus on conversations sometimes -- my friends and I joke that I get distracted too easily but the truth is that it's just impossible for me to concentrate on one thing for very long. Sometimes I can't even complete a sentence before I forget what I'm talking about, and people have to point out that I didn't complete my thought. My friends are just used to my "absent-mindedness" but I know a lot of it is caused by the depression. I completely lost interest in my studies, which made no sense to me because when I started I thought this was what I was meant to be doing, and it's only been since the meds finally kicked in that I was able to care even remotely about what I was doing. I considered a change of school and degree but I've decided to stick it out with the hope that as I get better, my interest and concentration will start to return again.
I'm glad you posted, and welcome to PC.
