Ok so I'm in my mid 20s and I'm really underweight. I've always had weight issues, so I guess I grew up to just live with it. I still live with my parents and just recently they went out on a 1 month vacation. During this time, I noticed I've gained almost 10lbs! I've never been able to do that before. Another thing I noticed is about 1-2 weeks after they came back, I ended up losing those 10lbs... Nothing changed as far as my daily day to day routines go (diet / activities and what not).
So I guess my question would be if stress can play a role in one's weight loss/gain. I don't feel like I'm stressed but, my mom always tells me that I think too much, which I do but, during the time I was all alone in the house, I felt pretty relaxed even though my parents really don't ask much of me. I'm not anti social or anything like that but I do like to be alone and thought maybe that's what it could be. Any thoughts? Ideas? Tips on ways to over come whatever issue it is I have? Thanks.
