goal weight

How do you determine a goal weight? I am now at what is considered to be a normal bmi on the chart. At just over 5 2 I am at 134 and wear size small usually on top and 8 jeans. Skin removal would probably take me down a size or two but cost will most likely be on me not insurance. So I did revise goal to 130. Friends say that's too low for me and think I am too thin now. Really confused about this. How did you set your goal? 

By my b mi I need to be at 142 and I'm 5' 7"

5' 2" and 134 lbs makes your BMI 24.5 -- that's within the healthy range of 18.5 - 24.9.  I think that's about as "objective" as you're going to get.  From there you just have to choose for yourself what you like, what you want, and what you can maintain.

Congratulations on your success.
