Hi Stella330,
I agree that it is a hard thing to do but not impossible. It will be alot easier with someone who can relate.
I have found that walking is what I enjoy most and know from experience that it's hard to stick to a workout program that you don't enjoy or that feels like a chore. I have tried numerous things (gyms, swimming, treadmill, stationary bike) but a hike through the woods or even just around my neighborhood is the only thing that I can do on a daily basis as I love to be outside in the fresh air. It really invigorates me. Perhaps you need to try different things or alternate your workout routine so you won't get bored. I know exactly what you mean about having so much to lose. It can be very overwhelming but I try to think of it as 10 lbs. at a time that way it seems more achievable. Once I lose 10 then I focus on the next 10 and I never look at the long term goal as it only discourages me.
I'm not really following a specific eating plan. I have just taken some info from different sources and devised my own plan.
Well, I hope I have helped you even a little and look forward to hearing from you again. By the way, I'm 30 and you?
Take care
