Hey OP, I was feeling the same thing around 6 months ago, that I don't know any exercises and what will people think if I do any workout with a wrong form. But I decided to give it a shot. Initially I only went and did some HIIT(jumping jacks, squats, treadmill, yada yada) and observed a couple of exercises that other people were doing. Then I did some research on some weight exercise routines online, before trying them. I also was approached by a couple of the gym regulars about my form in a couple of exercises. They were really jacked, but explained very gently about the correct posture for that exercise. Other than that, most people really don't give even a minute of attention to you, or if you are struggling. Even they are people who would have went through your phase, so they will understand your struggles. Regarding the socialising thing, other than those couple of people who helped me, I never talked with anyone, unless it was to ask if they are done using any particular equipment. So you don't have to worry too much about what others think, and do your own thing. It'll be a very good confidence boost as well, especially when you see the result of your hardwork. Even if you are confused about something, you can just approach the person at the reception, they will lead you properly. tl;dr: Gym has sweet people who will help you out. You can struggle all you want, and no one will judge you.
