How to fix this issue

i recently hit 2600 bullet and i wanna try for 2600 blitz now, i have to change my mindset from moving fast and keeping up on speed to actually outplaying opponents. But i came to a problem that has held me back quite alot and has been really quite frustrating 

MOUSESLIPPING:

In bullet it doesnt really matter that much but and in blitz and rapid one mouse slipp can throw the whole game away.

and this other one where i meant to play b3 and played b4 -_- https://www.chess.com/game/live/140695424270?move=17

these are just a few examples of what has been happening most other mouse slipps dont lose the whole game like that, it happens every 2-4 games and it causes more loss tilt/drop

My internet is good, my nerves are good im not old just yet, i simply have something called "Skill issue" How to get past this? this is the only thing that triggers tilt for me now i dont tilt anymore about simply getting outplayed or losing on-time. 

Please comment advice below, 

rapid and blitz are slower time controls so really make sure you put your piece on the right square. maybe in rapid you can move slower

Click, don't drag.

Probably the best advice for not mouse-slipping you're going to get other than simply moving slower.
And, congrats! 2600 is insane

agreed

2600 is a great achievement!!! Congrats Tiki!
