Adjusting weight loss goal

Hey everyone! I have been on here a little over a month now and I have lost six pounds, but I am pretty sure I have gained a lot of muscle so I feel like I've lost more. At the beginning my goal was to lose 50 pounds, but now I'm not sure if that is necessary and if I lost 20 to 30 more pounds I would be good. I feel like if I do there will literally be any of me left and I will just start to lose muscle. I was just wondering if anyone had any suggestions or thoughts on the issue.

Thanks a bundle,
Paige
