Don't feel bad. People can be real assholes. I'm sure ur an amazing person and deciding to go for a run is very good. Running is good for you but don't over do it. And don't listen to assholes.

hes an asshole

That guy feels like shit about himself; don't let him bring you down!

That's just cruel D: Ignore him, OP. He's a mega douche anyways. He's probably not in the best shape himself, or if he is, he definitely wasn't born that way. Keep up your hard work, it all pays off in the end!

All I'm saying is conceal and carry they won't laugh at that

Look at you go, taking initiative and doing something great for yourself. Seriously. Don't take it to heart, as hard as that may sound. This world is full of horrible people, it's just very unfortunate that you had to meet one this way. Keep at it and reach your goal. Then you can be the one laughing at him. You should be proud of yourself. Please keep at it, and don't let one asshole ruin your self-confidence. He's the one who has something to be ashamed about, not you.

Please don't give up that should be your motivation thirst on it:)

Don't let jerks like that get you down! Just remember, you're going to look great and people like that never make it in the long run.

How exactly does he think people lose weight? He must really suck at life if he needs to make fun of others taking positive steps in their life to feel good about himself. You certainly don't deserve that kind of pointless hatred from a stranger, but don't give him enough power to keep you from your goals. He isn't worth sacrificing your health or possibly shortening your life. I would run with music on though, loud enough not to hear him in case he comes back.

Next time just stop running OP. Stop, look at them with indifference and they'll leave you alone faster, then you can get on with your run in peace. Or even better, turn around and run the other way!
