Neck fat. 👎🏻

I<3Dolphins • I`m a 23 year old Military wife. My husband and I have been TTC #1 since November 13, 2013. ✨
I'm 23. I'm 5'9. I weigh about 233 lbs. I am considered obese (going by my BMI). I need to lose weight but I don't know where or how to get started. I can't sleep because my neck fat was choking me. (I know that sounds really dumb). 
I posted some pictures of me so you can see. 
I need advice and tips please. I really need to lose weight so I can sleep at night and feel better about myself. 
XOXO ✨
