Sheridan, your body is not ruined, you are young and will bounce right back. When I was 25 I had a miscarriage but I fell pregnant 3 months later. I was terrified of having another miscarriage so I did as little as possible (except eat) for 9 months. After the birth I had put on 5 stone. But I shifted it, I started the gym too and by the end I was slimmer than I had been in years and I even managed to lose the flabby tummy (don't think I'll manage that this time lol) I bet you can do this too x
