Weird GMOD Scrolling/Gun Glitch

So i was playing garry's mod ya know and then i decided to delete some addons i don't since i had a lot so then i go back onto garry's mod and kabloom Scrolling Is Not Working Weapon Hud Is Not Showing Up And when i pull a weapon from the spawn menu out i can't change it through scrolling though different guns so that means i literally have to go into the console to kill myself so i can get the Physics Gun back Please Help Me ;-;.
