Hi Asia -
You are DEFINITELY not alone, or the biggest. Have you seen our 300+ club, or the 100 lb club for those with 100 lbs or more to lose? You'll find plenty of folks who know EXACTLY where you're coming from.
In terms of fitting in exercise, there are LOTS of things you can do INSIDE, never braving that cold weather. I like doing strength training videos at home, but you can do Walk Away the Pounds or other home walking videos, or just turn on some music and dance or go up and down the stairs. Start looking at your house in terms of what you can do to be more active, and you'll be surprised how many spots show up! Exercise videos are inexpensive and might be a great place to start while you wait for it to warm up.
For eating advice, look around! We have so many forums here by eating plan, each with great advice and discussion. So keep posting and exploring. I can't wait to get to know you better!
