Welcome to CB! I'm glad that your desperation led you here, as I think it will be helpful for you to hear from parents and coaches outside of your gym, and that your perspective will be valuable.
I understand your dislike of the time involved, the expense, the competitive moms and dads. However, based on the 2 threads that you've begun so far, I honestly wonder a little about the gym in which your dd is involved, and think that some of your dislike may come from there. As I said in your other thread, my dd is also on a fast-track, yet her teammates and her do not have bedwetting issues, and her coaches and gym owners take time to talk to us.
As far as the time goes, we homeschool (a choice made before our 4 kids were school-age that had nothing to do with gymnastics, btw), and one of the reasons that I'm glad that we do is that my dd is able to just be a kid for a big part of the day, playing with her other homeschooled friends and siblings, etc. If we didn't homeschool, I might feel differently about the amount of time that my dd spends at gymnastics. (I'm not suggesting that you homeschool; I'm just saying that I understand how you'd be concerned about the time involved. Although, most of dd's teammates are not homeschooled and seem to be well-adjusted. And, both schooled and un-schooled gymmies do gymnastics for fun even when not at practice, which suggests to me that they are spending the time the way that they want!) Even though our dd has more down time than those in school, she has at times missed gym to go to parties or something, and she still is dedicated to gym and does well at it.
Last night, my husband and I were talking about competitive parents with another gym parent, and we told him stories about theater parents (our oldest dd is heavily involved in theater), who can be as obnoxious as gym parents, who can be as annoying as scholastic achiever parents (I used to be an educator in public schools and have seen how competitive and mean they can be), who can be as awful as soccer parents . . . You get the idea. It's everywhere, unfortunately. We've dealt with these parents ourselves, and both my dh and I are weary of it. Hey, secretly, against my better intentions, maybe I'm one of those, as well, sometimes, as I admit that I've silently wished before that a competitor might make a mistake at a meet if my dd didn't do as well as she wanted, or if I've thought that my other dd would've been much better at a part than so-and-so. It's ugly, I know--I hate that I've even had those thoughts--but we can only keep checking ourselves and trying to surround ourselves with positive, encouraging, hopefully genuine people, no matter what our children decide to pursue (even if your dw is the only other positive, encouraging, genuine person you can find where you're at

).
And, for all of the negative, I've seen a lot of great positives in my dd's life. Her strength--and I'm talking psychological strength and strength of character here, not physical--, positive and valuable life lessons learned, her confidence and belief in herself . . . I could go on and on. As long as your dd continues to love the sport and grows in it in a healthy way, I think you may start seeing more of the positive.
Enjoy CB, even if you don't enjoy gymnastics!

You're welcome here.
