Hey Butterfly

Depression can cause something that has a whole spectrum to it, a big network of things that are considered the same phenomena. It can make you unable to attend to anything ever, but all you can do is go to your comfort zone and get stuck there. It's no one's fault, it's depression and its effect on the individual
I myself do both, I'm always in bed, and I always check on things with my computer, and most of the time there isn't anything to see, but I always seem to be searching for something that I can't find and actually never did find, hence the idea of no pleasure coming from that.

I do think that upping the dose was not a flawless idea on your doctor's behalf, because meds can be toxic and their side effects can get more severe causing the patient to feel worse. The idea of not seeing any difference alone can make someone feel worse, and I can only imagine how hard it was on you

I think all depressed people need someone who listens, understands, and isn't critical, and in my opinion that's the best thing to happen, and I wish more people are aware of that.

Hope everything goes well for you!
