body confidence

Heather
This is my first post but I love reading all the support from this community. So I have a question. How do you ladies stay confident about your body image? I used to be 140lbs, but then I started working out and got to 160lbs. I was fit but wasn't too confident in my body. Then I got pretty damn sick and gained 35 lbs. I am now 195, but I feel amazing. I haven't been sick in a while. I eat good, workout, I'm active and social. My life is wonderful. However I can't shake the feeling like I'm less of a women because I'm bigger now. My boyfriend loves it but encourages me to at least stay healthy. Which is understandable considering I struggled so bad when I was sick. I have a lot of things coming up like my sisters wedding (which I can't fit into the dress I got) and a Mexico trip. But even though I feel like I'm better this way (health wise I truly feel like I am), I can't shake the feeling like my friends and family think less of me because I'm not the average sized fit girl is used to me. 
How do I get my confidence back?
