Are you afraid of going to the gym? do you have a feeling of fear or shame when you anticipate going to the gym? Don't be. Working out in the gym is a selfish process by nature. Everybody has to focus on themselves in the gym. That is the default environment. So just do your thing there. Take incremental steps moving forward. I would friendly suggest you to take baby steps that will bring you closer to your desired obtainment. Go to the gym to drink coffee, then go back home. Next time, research the utility of one machine. Watch youtube video's about it, then execute that one exercise. Then do two machines, etc. You can do it. Have an enjoyable listen! I hope it's desirable for the ears.
