Welcome Synderella!
I gained over 50 pounds with my first pregnancy 39 years ago. I'm proud of you for addressing this now. I roller coasted up another 100 pounds over the decades- so stick with it this time, save yourself from the physical reprecussions that will come with age and years of wear and tear.
You are blessed to have somewhere like 3FC to come for support. There is so much inspiration here and so many ways to lose-take your time & choose what is healthy for you-compatible with your life and beyond the food- exercise- address your emotional issues. That is the key I've found this time. OH! And have fun with it- Weight loss can be an exciting journey.
