Thanks for the response as well as the complement! I think I may take your advice on starting at 10 for now. Every pound seems to show up on my body from being so short so big numbers feel so much more daunting!
As others have already said, start small with only a few pounds to see if you think it really is for you. Don't want to dive straight in off the deep end and realize you don't really want to do it!
In my opinion, you could try for 200, considering your height. I believe it would look nice on you; also it would not make you excessively fat and difficult to do normal activities. Whatever you decide, I wish you the best!
