<human>: Can you condense the text into a few key points?

I've been suffering from anxiety for the past few months and its gotten to the point where its been interfering with my daily life. I am married and my relationship with my husband has been incredible. We had sex about 4x a week for years and have always been satisfied with each other despite our fluctuations in weight. 
   Lately I have been focusing all my strength on recovering from my panic and anxiety by seeing therapists, psychiatrists, reading self help books, posting on forums, taking medications etc. Its been a very difficult past 3 months. Needless to say, it has affected my relationship with my husband. Now, he has still been wonderful to me and has been giving me much needed support but our sex life has definitely been faltering.
    Since my anxiety issues started getting worse, I've taken to eating junk food to help me "feel better" (big no-no). Obviously, my weight has been affected and I've gained about 10 lbs in 2 months and look extremely bloated. I normally cook for my husband and since I've basically stopped cooking, his weight has been affected as well and he has started overeating to "feel good". 
    Now, he has always been overweight. I married him while he was weighing 270 lbs (he's 5,10) and he now is weighing 315 lbs. We've spoken about his weight before but its such a sensitive issue he normally tries to work out for 1 week, see no results, then goes back to overeating. 
   His weight has never really bothered me because he is amazing at sex. Seriously. But lately my libido is way waaaay down and he is always asking to have sex. I can't bring myself to say that along with my libido being low, I suddenly find myself unattracted to his body. Even worse, its been 2 weeks since we had sex and last night I had the most incredible dream about Zac Efron and I fucking. I woke to my husband fondeling me and me pushing his away. 
    I feel horrible. I know I'm not innocent in this whole thing and I've definitely gained weight since we first got married (I used to weigh 115 and now am at a whopping 173. I'm 5'3). What should I do??
