I feel like I'm starting over need some moral support

Hi every one ... My name is sasa I'm 38 yrs old and I'm an active runner my last log miles was this August 12miles and two days after I broke my fibula roller skating, doctor told me I have very strong bones so it will heal fast, I was in a cast for about 3weeks but on crutches for 4 weeks and now I'm wearing a boot.. It's very frustrating cause I'm used to waking up and going running or hitting the gym which i haven't been doing this pass month... I've manage to do some abs and push ups and pull ups at home but now I've decided to start back going to the gym because I miss lifting .. My doctor told me no weights on the leg for the next 6 weeks,. My main concern is that my birthday is soon coming an Ive realize that I started gaining weight which freaks me cause I've worked really hard since I was 25 to lose weight and stay in shape ...

I've been able to manage my weight by eating right and exercise but now my test is here... It's been some what tough not moving around as I'm use to and I find my self sometimes eating what I shouldn't .... So I feel like I'm starting over... An it frustrates me.. Any help or advice is appreciated..
