I'm so effin annoyed

So I joined WW because I feel like my obesity is causing infertility. I'm frustrated to say the least because of course my 1st week was me starting my period so I gained 4. Now I just need support. I want to be pregnant so bad with my husband.i know it sounds crazy but I have never felt so negatively about my self. I know I'm fat. I'm 260.4. Hence why I started a dieting program. But growing up, I was a skinny mini. The weight didnt start adding on until I was 20 and in nursing school. When I failed out I gave up on everything. Nursing school and all. I gave up on my body. I was 136 pounds back then and I gave up. Now I'm 260. Imagine your husband knowing you at your skinniest and now try seducing him.....
