Doing my first Orangetheory class this weekend and I'm super nervous.

I'm about 20-25 pounds overweight and I don't do the gym because I always end up quitting. I really need to get some exercise because I have trouble anxiety and being out of shape doesn't help. I feel like my world has shrunk so small that it's starting to feel suffocating. I have to get out and do stuff even if it's hard. I'm not a social person but I have to get out. Also I joined a zumba class so I'm doing that tomorrow. I signed up for it in spite of my anxiety. The hardest part is showing up and I did it. I just have to keep showing up.
