Having a hard time staying positive

I have been obese for a good part of my life. I've recently decided to lose weight and although I'm very proud of my accomplishments, I'm still finding it very hard to stay positive about my body. I've lost a lot of weight and I'm dealing with very bad loose and wrinkly skin on my stomach and arms, stretch marks, everything. I'm just very uncomfortable in my body. There is even times where I don't want to leave my house because I am just embarrassed and uncomfortable. Surgery seems to be my only option, but that is not an option for me at this point for several reasons.

I hope there is someone here in this community that understands and can give me advice on how to cope.
