i don't like going to the gym but, what can i do

i only go there to swim for an hour, but its what i have to endure whilst i am there...annoying music played all the time through the speakers, so i have to put up with that whilst getting changed in the locker rooms, ready to go to the swimming pool....then its having to put up with all the noise and banter from young lads who go there...some who clown around and are just ''in your face''.......there's this gym cleaner who i've took a disliking to as well....african lad or maybe just black british....but he's often near me in the locker rooms, picking up stuff off the ground...or moving the benches around...i suppose its his job...but he just irritates me, even aggravates me and annoys me sometimes.


all i want to do is just do my hours swim, get out, get showered, dried and dressed then get out of there and come home...the gym is only across the road from me...but its still hard for me to go there.....yet, i have to go to keep my fitness up, lose weight and manage my type 2 diabetes......so i'm tied to going there in a way.

what can i do?
