<human>: I feel that I can be that friend that anyone can come to if they need anything,but I have one particular friend that seems to take advantage of this. She  never seems to pull her own weight. She constantly complains about not having money, so I would pick up her lunch. Now, it seems that she's come into the habit of inviting herself into my plans and expects me to pick up her lunch every time we go out. I know she doesn't have any money,so I feel bad and end up obliging because she won't order anything and I end up feeling like an asshole eating in front of her.

She has also dropped the ball on a project we had due last week, when all she had to do was write up a short presentation while I did all the work.

When she found out I got an interview with a hospital, she called HR and told them that I had an interview scheduled with them to which they granted her an interview too for the same position because she insisted. She then suggested that we ride together as she has no money for gas and doesn't even offer to pay me back.

I'm feeling immensely resentful as she got offered the position, even though I had better references and was very well qualified. HR said that it was because they were afraid I would not be a long term employee as I was an excellent candidate, but seemed to be very ambitious with my goals in going back to school and advancing my career.

Today, I felt bad her boyfriend was saying that he hasnt been eating anything but cracker because they couldnt afford groceries. I cooked them some Korean BBQ along a whole bunch of other stuff I sent them(I'm a great cook,I swear!) and all she could tell me was that her bf took a few bites and threw the rest away because he wasn't into asian food. I feel that my compassion just gets the best of me and others just take advantage of it. As much as I help, I feel that it sets me back more than anything :(

Can you condense the text into three sentences or less?
<bot>: I just feel like I try and try to good for others, but I end up getting the shit end of the stick. What am I doing wrong?
