New girl trying to fix an old injury

Hi I'm Ariel and I'm 22,

I wrecked my knee very badly about 6 years ago and there is really nothing much doctors can do about it, so I used to just fight through it and I eventually made it worse. I was a very avid hockey player along with rugby, lacrosse, mountain biking, skiing and hiking to name a few.
I am extremely outdoorsy! I have a decent workout schedule which I try to keep going 7 days week at a decent rate and on the days I don't feel up to it I do a Zumba dance workout because honestly I'm a terrible dancer but it is fun and fast and kills alot of calories.

My biggest problem is my eating habits, I have a portion issue where its not that I don't eat healthy its that I eat too much of my healthy dinner. I also have a boyfriend who is extremely fit and has a crazy high metabolism which means he has to eat high calorie delicious food while I can't so much. He tries to motivate me but honestly he just tells me what I do wrong and then I feel awful, but I know he tries.

I gained a lot of weight when my knee went down, I lost mobility for almost a year, I was on crutches and on a couch for most of that year and a bit after and I just packed on the weight, I have taken off 20lbs so far but I'm still 40+ lbs away from my goal weight. Honestly I just want to be healthier, I want to take the weight off my knee so that I can get back to the things I love most like riding my horse and hiking with my boyfriend. Its nice to have support, people to complain to I suppose when you don't want to workout or eat right that day or when you'd rather go to a bar eat wings and drink beer and watch hockey then eat a salad and drink tea on the couch.
So if anyone wants a new friend, or someone to ***** too and some additional mutual support I'm your gal. We are all trying to get somewhere its just easier for some then other.

Cheers,
-Ariel
