need the support and motivation

I started mid January on my journey to lose 70 pounds and as always start off so well then something comes up or I just straight up lose all motivation! I over eat for sure and eat emotionally. I did so well the first month but then my birthday rolled around. I told my self just for my birthday id go fat kid crazy and eat anything i desired but of course in moderation. So now here i am off track of what i started and need to get it together. I haven't gained any weight back and still down 18 pounds. My starting weight was 236 and i want to be 160. I do love exercise but don't have the money for a gym membership. I currently do insanity and some Jillian Michael videos. So if you need the motivation as well id love to help!
