Internet gym buddies

Backstory: I have recently over the past couple of months, gained some weight. About 20 pounds...that went straight to my stomach. You can hardly tell if I wear a big shirt (which I started to do.) For the last month, my grandma (who I love but can't be with for more than 1 day) has taken every chance she could to call me fat and to tell me that I used to look cute.....

Today: I want to lose weight and make her shut up. I know revenge is probably the worst motivation for losing weight but I am so tired of the chubby and fat jokes. I need someone to help motivate me to go to the gym and actually start eating right. Maybe they are going through the journey as well or have been through the journey already. I'm thinking we text or Snapchat each other just checking on ones progress and making sure that each other is okay.

I really need/want this guys. If I end up with a friend after this then good.
