Help Me please, my biggest enemy is doubt

I´m on laptop speakers right now, i can give it better critique later on. But what i can hear over the laptop speakers is heavy high end fizz on the guitars. Cant really judge low-end etc. so i´ll get back to you later!
 
over midrange on the guitar's which kinda sounds boxy..
Bass and guitar are fighting with each other
overheads are super harsh
too much SSSSsss on the vocals
