Hey, thanks for your clarity in this message and I hope i can be of some help.
To start with: "I feel like I'm just some lazy person because if it were depression the meds would be working and I'd be full of life and energy" is NOT true. Not at all. The meds can either be to give you a little boost so you aren't suicidal all the time, or to give you breathing space and then with the breathing space they give you, you can cope momentarily until you get yourself sorted out.
I'm not sure that made much sense but basically, the meds aren't meant to be a cure like that. They give you space and calmness of mind or a boost so you can then cope with trying to sort out the underlying issues.
Yes, you already know about anhedonia and what you are experiencing is NOT laziness but depression. Yeah, maybe laziness is playing a small factor but it is not the main factor. It is depression.
I suggest you go to a psychiatrist or counsellor as soon as possible. The sooner you do, the sooner you'll be feeling better. It will help you go over underlying issues that may be causing you to be down (we all have them) and if not, it will at least help change your outset and attitude so things can start viewing things as more exciting and WANT to do them. I wish you the best of luck.
