Yeah its definitely hard to get going again, but you just have to decide you are going to do it, pack your bag and go, and keep going until you are back in your groove.
What are you doing on th TM, elliptical and steps - I find that doing interval training at least keeps me entertained for the most part - i can't just set it on one speed and go for an hour.
Dont be scared of the cycling - try out the stationary bikes a couple times, get a feel for it, and then try a spin class. I was maybe close to 300 lbs still when I started spinning and i was terrified because i was definitely the biggest person and I didnt know if I could do it, but I went, and I did it, and i LOVED it. Its a high energy, upbeat environment that's engaging and definitely takes away the boring aspect of working out alone.
What about group exericse classes? I do those occassionally to break up my same old routine. You can get creative - dancing, kick boxing, etc if they are available.
