Hypothyroid problems

So as the caption says I do have Hypo , and basically growing up I was in sports and was fit , now getting fat and my skin is so oily I can't stop eating , I can't sleep at night. Like I'm literally eating with my eyes. I'm gaining weight fast and nothing fits me also I'm having a hard time even trying to look at myself in the mirror , i can't deal. I'm 23 days late in my period. I need to take control of my life because this is not the road I want to travel on :( . Any suggestions in how to loose weight. I'm already eating healthy and starting cardio.
