Depressed

A hobo came up to one of my friends once and asked her for some money. She had no cash so she told him the truth (as you did to the begger bastard). Now this hobo was some mean shit and he started saying crap to my friend that only a girl would take seriously. "No money? did you stuff it in your thighs? He also commented on her "chubbed fat underneath the boobs". He was an ass hole. I can assure you that my friend is no where near fat, or average. She's pretty damn hot but she had the same attack as you and she went depressed all over me. It took me a while to get her to understand that hobo was a bastard. Did I beat his dirty ass out? Yes, but only to a point where he actually said sorry. Other than that, just know that bastards like the guy who attacked you emotionally was being a jerk and doesn't even know wtf he's talkin' about. Don't sweat it. If you know you look good, who needs a comment from a begger? I mean if he had any type of value, he would have made something with his life by now. Don't you think?

well first off bums are very mean when and want to hurt the person in someway if they don't get what they want. (for you he attacked emotionally) don't let one person who was angry make you sad. (the guy could have done it thousands of people and your just one of them) I always try and ignore beggars or at least say just plain no sorry.
mood boost- you can always hang out with your friends for a boost. or go out an meet new people preferably people who would care about other peoples emotions. hope I gave a bit of help.

he's just pissed off.
don't let it get to you,
he just wanted to make you feel bad.

Dont let other people or situations control you, and your feelings.
It sounds impossible, but did you know we can choose how we feel? We have control of our own feelings, and we can decide what to feel.
So someone made you feel bad.
You can either:
1) Let him ruin your entire day, and mope around because of some douchbag, who doesn't even mean anything to you.
or
2) Brush it off; suck it in; and say, Whatever. You don't know me! *snap* And continue living your day happy.

If you stick to the first one, then you are letting this guy control your whole day. That doesn't sound right, don't you think? Letting some homeless dude ruin your day? He's not worth it, and no one is for that matter. So learn to take control of your emotions, and feelings. There are consequences in EACH decision we make (including how we let ourselves feel), so it is up to you to make that decision. If you want to be happy, then don't dwell on negative thoughts, and happenings.
Its not easy to do, but if you really want to, you can do it. good luck.

P.S. Try eating chocolates :) That ALWAYS puts me in a good mood. Or watch a funny movie.
