Wouldn't it be embarrassing if I died in my gym's bathroom?

I joined Gold's Gym in Spanish Fork a few months after Evie was born. I was sinking into a deep depression and needed something to motivate me to exercise, because like I've said before, it's either exercise or medication. I convince/badgered my friend Karen (who in no way needs to go to the gym) to join with me and we started working out there a few times a week. Then gas prices skyrocketed and I found that driving the 20 miles to Spanish Fork was really costing me a lot of money. I started just going a couple of times a week and eventually it was down to Saturday mornings only. Obviously, the $29 a month I was paying was not worth it and so when it came up for renewal in September, I cancelled it. I had been running three times a week all summer and was really enjoying it and thought I'd just continue that through out fall and winter. Well guess what? In the fall it's dark at 5:30 a.m. and damn cold! I kept at it but one morning I got up to run and it just seemed creepy outside. Like, zombie creepy. Ryan didn't like the idea of me running alone in the dark anyway, so I quit. Payson has Dumbbells Gym which is very small but it has what you need. Plus it's only five miles away, well it will be when the horrible detour gone. Grace's teacher told me she taught a 6 a.m. spin class there three times a week and I like spin so this sounded perfect. I only pay $20/month and it's month to month, no contract. I went to my first class last Monday and it was going fine until about halfway through when she had us take off our bike seats for a couple of songs. About halfway though the second song I suddenly thought, "I'm going to pass out or throw up!" I went into the bathroom and stood in front of the sink with my head down. Every time I lifted my head up, I felt like I would puke or black out. Finally I sat down on the floor and put my head between my legs. I kept thinking, "This is going to be so embarrassing when they find me in here unconscious." Luckily after about ten minutes I was able to stand up and go back to class. You may ask, "Why did she go back to class?!?" It's because I didn't want to look like a puss who had to leave her first class. Why can't I have that kind of determination in other areas of my life?
