Ok since a week Im getting smaller and smaller. No its not mental I get comment and my clothes who use too be tight are now loose.. every bodypart is smaller..

the thing is.. I weight the exact same weight.. and no more fat on me.. same strenght.. I try to carb load, drink water.. nothing.. wtf??

whats happening ? Its killing me

Maybe your clothes are getting worn out.

Any serious idea?

by no more fat I mean I didn't gain fat that would explain weight gain..

I dont consider myself a beginer' ive been lifting for 2 years and a half, Im 5'10 210 pound 13% bodyfat.

everything look smaller and flat.. what the hell

You may have just lost some fat and gained some muscle in return, as fat weighs less than muscle and muscle weighs more than fat. So a small increase in muscle and a noticeable decrease in fat may have occurred, hence the size decrease. If it really worries you that much go ask a doctor and get a check-up.

no Im not leaner a bit and Im 100% sure of this.. every muscle of my body are smaller I can see it in the mirror and I cant feel it by the touch.. god I even feel lighter but I weight the same,, its like a ballon who explode.. what the hell.. I was thinking about going to a doctor but what he gonna do about it.. he probably doesn't know shit about this.

Your weight is the same. Your strength is the same. You seem to be feeling OK physically. There is nothing wrong with you dude. Sometimes my shirts pants fit different on different days. I'm about your size at 5'11 208 and I can relate to your issues. Don't stress about it.
