<human>: Can you provide a brief rundown of the text in within 3 sentences?

My husband and I have been together, as a couple, for almost 10 years. Our relationship, like any other, has had its ups and downs, especially since we started dating as young as we did (I was 17/18, he was 19). But I think we've both grown and we're both committed, awesome adults. 

The issue is that I have horrible, horrible mental issues, most of which revolve around my insecurities, my almost non-existent self-esteem, and a plethora of other self-worth issues. I struggle daily with what or who I am, what I contribute to society, if I'm worthless or not. I feel ugly, fat, and stupid constantly, and I feel that I'm not worthy of my husbands love. I question his love often, as well, because I cannot understand why such a great man would want to be with somebody like myself. 

Recently, he told me that my issues are wearing on him and if they continue, things between us will not work out. We've had many fights started simply because I can't accept or understand his love for me.

My biggest fear is him leaving me; I depend on him for a lot in life, and I think being left by him would be a blow I could not handle. I don't know what to do to solve my self-worth issues, my numerous security issues, and my complete lack of self-esteem.
<bot>: my insecurities are eating me alive, and are starting to effect my marriage and relationship with my husband. I don't know what to do.
