What am I doing wrong? (2 stories-roommate/office politics)

gah…* sigh *... ok

Every single day, I try to improve myself as a human being.
Every single day, I try to grow as a person. I try to learn from my mistakes, and I make a lot of mistakes like a lot of people. I am by no means perfect.
Latest examples:

This is yesterday when i am coming out of my room

Her:…didn’t you hear me?
Me: no what?
Her: i was calling you.
Me: no I didn’t hear…
Her: well i was calling you, and i was knocking
Me:…no….i…
Her: hmmm….(rolls eyes, walks away)

are you kidding me, i have told her numerous times that when i am in my room infront of my computer, that i have headphones on 99% of the time, therefore can not hear people with the door shut and my headphones on.
still this happens. Does she think i am lying, i know this sounds lame compared to the problems we are facing in the world today, but if i can’t comprehend things like this, how can i save the world?

i show up to work every single day, just like a lot of you guys. I give 110% every single day and have single handedly saved the company 100’s of thousands of dollars. not only am i barely able to buy food for myself (i sit in my room all day long and only drive to the grocery store) You probably won’t believe me when i say i do not buy a single thing…
anyways, that was just to let you know that my world is unjust, and i am being treated extremely unfairly.

…so at work, i show up early every single day, work when at lunch and when i’m not on the clock and don’t waste ANY TIME. and work faster than every single person there (except 1 girl in a different dept. who has better shortcuts than i do)

so these 2 geniuses talk about how the boss told them NOT to clock other people in, and are unsatisfied with their life and how they are not gettting special treatment

And i tell them: Hey..I have seen you guys do it before and everyone knows that you should never clock other people in or out from break/lunch.
then they start giving me sh*t. I point out the fact that they show up to work late EVERY SINGLE DAY, and the only thing their supervisor cares about is sucking the boss man’s you know what and to look good in front of him, not caring if his people do the work…
people watch TV SHOWS while working, and go on social networking sites ALL THE TIME, and text each other ALL THE TIME during work hours.

And during my review (2 days ago) my boss calls me negative and emotional. Are you F*CKING KIDDING ME. Just because i am Passionate about my job, and CARE for things, and say “HEY do not pay $$$ much for this machine cuz it is a waste of money” I get accused of being negative and not giving it time before we figure out WHAT this machine/software is capable of.
I do my work every single day and KNOW these things inside out, Unlike some people who just want to waste 2 months on a bs project that they know will go no where… (btw for the record, we have paid (on numerous occasions) for things (software etc.) that cost tens of thousands of dollars and NEVER EVER used them…)

…..sigh .... I have been doing yoga, eliminating everything and everyone that is negative in my life, and giving up ALMOST every addiction that i have (2 left) but it seems like i still can’t let things go, i get stressed and frustrated….

can all these people be crazy or am i the one who is not able to interact with others???

What am i doing wrong? can someone explain to me?
