Why am i incredibly unmotivated to do anything?

I have been diagnosed with depression and ADHD but i am taking meds for it. It didn't change a single thing.

Life is not bad either. If i could try i would probably achieve anything i want, but i just can't.

Life itself seems so shallow. I want to do everything i dreamt of but it seems so impossible to lift my finger for it.

My days go of by me sleeping for 14+ hours, and then sitting all day.

Is there anyone who lived through this? and solved it? or any remediations?
