I was very much in the same situation you described. When I first started going to meetings, I got a sponsor and did some work on the 12 steps. For several reasons, I could not connect with a lot of what people say you need to do stay sober. Eventually, I just decided to attend the meetings cause I was getting a lot out of them. I rarely shared. I learned a lot just listening to other people at the meetings. I was able to work some of the 12 steps into my plan to stay sober that I understood and worked for me.
Besides, I noticed that it's almost the same people that share. I got the most out of the people that rarely shared but when they did, I could relate to it. Many of the people at the meetings I went to never shared, so you are not alone in how you deal with the meetings. Many probable are doing the same thing you are doing. I say keep going if it helps you stay sober. John
