Trying to find a way out in Maze of my mind

So, here is the thing with me, I feel like I am in this unending cycle of mental and physical behavior, in a way it feels like as if my life is dictated to go on loop where I constantly try to do better and be better.
Just like everyone out there I also procrastinate and sometimes end up not achieving my goals, which I have set for myself. I also have these sudden boost of energy and motivation that may get me started on something but halfway I’ll leave it there. That is it, I may not even finish it. I know desperately well what are my priorities and what is important at the moment and what is not. I also know that I need to work hard to achieve that but I can’t get myself to get up and do it. even if I manage to do that, I end up starting blankly at the book or screen, just like that. It’s so frustrating and the thing is I can’t do anything about it. Everyday I set a target and everyday I fail.
Now I know for many people it something they can relate and probably some won’t find it that disturbing but I do, because
1. I have anxiety and literally anything I do is challenging for me at my worst. But I am also depressed that means ordinary things can also trigger me to go into my shell or become distant. Since my education matters a lot to me, failing to study or achieving my set goals really bothers me. It’s not a thing about one or two weeks , this has been going on for months.
2. It’s not just about my education, it’s about my health as well. literally anything or everything I do. I barely make through a day sometimes.what hurts me is that before this whole thing started I was fairly confident person and I was satisfied with it. I was at the top of my class and would get high grades in all subjects. so it kind of feels like I lost something when I look at myself now, I can surely improve. I try but in the end end up feeling more lost and empty.
so I concluded a long time ago that I need to stop this. put an end to this type of lifestyle. So I started experimenting and tried to figure out a way to help myself. sometimes things work out sometimes they don’t. However I still haven’t been able to get out this maze of my mind.
surely one day I will, till then I’ll write my thoughts away.
