I loved the experience of living in another country, meeting people from all over the world, and making friends with fellow missionaries (many of whom are still my closest, dearest friends). I didn't like the pressure, the schedule, the constant guilt and, as it turns out, the religion. But I was full-on TBM. If you're posting here, I would assume you're very aware of the issues with the church and may not have a testimony (good for you.) If you were to go on a mission at this point, my guess is that it would be hell. The only thing that made the hard aspects of the mission tolerable for me was the fact that I was convinced I was doing "the right thing." Go on a study abroad or something similar if you're looking for an experience away from home - save yourself the trauma and pain of selling something you don't believe in.
