Hi Alicia!!!
And welcome to the 100 lb club area!
Short term goals are not always time based. Some are, and it depends on what the person feels they are able to lose in that amount of time. My short term goal is not time based. It's just a smaller number to look at other than my overall goal, which would be constantly overwhelming.
There are size charts which can give you a rough estimate for about what someone your height should weigh, but often a doctor knows best what is healthiest for you.
Definitely make use of the forums. Keep us all updated on how you're doing! And congrats on the weight you've lost so far. Simply fantastic!
