I don’t feel comfortable driving to shul anymore

I’ve been going to Chabad for almost 2 years and the shul I go to is too far away to walk so I normally drive there. There are other people who drive their too. However I have been feeling really guilty about driving on Shabbat lately and I don’t think I can drive on Shabbat anymore. I don’t want to say that’s why I don’t want to go to the rabbi or the other people who go because I don’t want to make people feel bad.
