I had the same feeling when I started, I'm 5'10 and was about 220 with pathetic strength. I think I started with 85 on bench and it took me forever to get 135 for reps. I felt like I should be able to lift and do more.
The biggest thing that helped me gain confidence was actually having a set program with meaningful structure to follow. For me it happened to be Stronglifts.com 5x5 while reading Starting Strength. Once you start adding weight every week and notice your body getting stronger and looking stronger you won't give a shit about anyone else in the gym. Now I go in confidently knowing what I want to achieve. People look at me funny for doing things like deadlifts (the new University gym I'm at since moving is literally all people doing 6 variations of curls every day and maybe some bench/incline) but who cares.
I've been doing this program since late March and have made quite good progress, although not as much as I've wanted, but that's the best part, you continue to work toward goals and feel good about it.
Good luck.
Edit: Just wanted to say, really commit to this for a few months, don't expect miracle results in a few weeks (although some changes are possible). I'd say find a program you like and do it for 3 months minimum.
