Gym insecurities

I have a question for you girls! My boyfriend and I have been going to the gym more and more as this year started, we got together last summer and started going to planet fitness together right after we met. We try going every other day now. I am in good health, I just want to loose some belly fat and gain muscle. Although every time I go to the gym I feel totally insecure. It causes me to not do some of the machines. I feel like every time I work out people are just staring. So my question..am I the only one that feels insecure when there? And if so how can I gain my confidence there?

I always tell myself the woman who are really fit at the gym have been working out for who knows how long and when they started they were just like everyone who first starts working out, with possibly being insecure. They are always so confident and I want to have that confidence in me even if I’m not ripped haha. And I always say that everyone is doing their own thing at the gym, I don’t stare at people for more then 3 seconds..no one is going to stare at me either.
