Starting a diet..again

I have been struggling with weight ever since I can remember and have gone through so many diets and for a few years managed to stay at a good weight with trainings 3x week (I was doing floorball competitively), but then I went to uni and the freshman 15 soon became freshman 30 and since I cannot do floorball anymore I am now trying to find motivation for just regular workout and healthy diet to hopefully get back to my initial weight.

I am looking for friends who can help me keep on track and we can also keep each other motivated! So add me if you want
