hello all. apologies in advance for the long post. some years ago i joined a company with a terribly toxic atmosphere and for some reason, stayed for several years. in that time, i became a nervous wreck, could not sleep without medication and put on a pile of weight. in the last few years however i was fortunate to find a job that i love, in a workplace that, while not perfect, is still great. however, the damage all those unhappy years did is still with me. so after years of relative inactivity (i used to be very active in my twenties and early thirties due to the nature of my job) i am joining a gym for the first time. and nervous about it. so for those of you who go to a gym, what should i expect? i have terrible memories of PE at school, so i'm a bit apprehensive about things like, where to change, privacy, what sort of clothes do you need, do people judge you by the way you look, do you ever feel like you're on "display" or do people just ignore other people, can you just go in and do your thing without having to interact with a trainer, etc. i know my concerns must sound so juvenile and silly. but i really want to do this for myself and am struggling to overcome a deep-seated shyness and dislike of being "exposed". any advice would be much appreciated.
