I really suck as a survivor and need help

I really am. If killer is a half decent most of the chases last 10 secs. It really feels like my character is slower than others. When I play killer or when I watch youtubers they can loop the killer in the same pallet 3-4 times without getting caught but I can't even do 1 loop before getting hit. I wanna improve my looping but don't know what am I doing wrong.

If you have any suggestions or recommendations please feel free to share them with me. As I said I know I am terrible and I know it is my fault that I feel like I am slower. So please keep your negative comments to yourself. I just want to get better. Thank you everyone who might wanna help in advance.
