You should probably think of the game in a positive way, so that it helps you feel better in return.
Learning how to tablet won't be any obsticle at all; especially if you remain complete shit at mouse, ehat do you have to lose?Money i guess.
Tablet might not be the answer for you #mousemasterraceI'm already tapping with my right hand and mousing exclusively with my left hand. I single tap currently because double tapping fucks with my head, though I've heard it's impossible to get "good" at the game without double tapping.
If you're going to buy a tablet you'll either:
1: Have to learn how to tap with your right hand
2: Have to learn how to play with your right hand.
I'm a lefty myself and bought a tablet a while back. Learning "how to tablet" will be a bigger obstacle than playing with your mouse tbh.
Just try to enjoy the game, and don't force anything. If you're not having fun then stop playing.
