I Need Real Help.

I need help. Lately I have been having this problem where my mind and my hand are out of sync, let me explain. Lately my hand has not being doing what my mind tells it to, like the game I just played I had so many times were I thought of doing something but didn't. Example) I am in a mf ult I tell myself FLASH, HEAL, DASH, but I don't do any of it, or I tell myself go back or go in and I don't do any of it. It's almost like my mind knows exactly what to do but my body wont do it. Like I know how to farm a couple weeks ago I could get 70-90 by 10 minutes now I get 50-60. A couple of weeks ago I could outplay like a god, now I cant outplay someone I have the advantage on. Also, that's not the only issue I have, when I am fighting all i focus on is the fight. It is the weirdest thing ever it's kinda like the world around me stops and the only thing my brain sees is this fight. I also don't see my hp or my map and end up dying cause I lose sight of everything else. Not to mention how bad my map awareness has gotten and my decision making and my all around play. Pleas help me this is really messing me up. Please give me help should I play more (played 10 games today) Should I play less, should I take a break, should I get glasses, should I meditate, anything that you think will help me. Please and Thank you.

P.s I have read through this and I don't expect you to know what I am saying unless you have went threw these problems because this is confusing.
