I understand what you mean. Nothing we do is ever good enough, is it? No matter how hard we try, life only slaps us down again. I know because I am there with you. You are not alone.
My situation may be somewhat different but I can empathize. I did everything "right"... I graduated college with a BA, struggled to find professional positions, settled for call center bull shit jobs out of desperation, set up a savings plan, and lost everything I saved to my ex, (pro-tip: NEVER agree to joint accounts.) I finally got a "real job," although I had to accept pittance wages to do it, and then I got screwed over because I was forced to be a "contractor" but not really. I didn't get to set my hours or rates, but management got to play with my hours as much as they like. I had to pay my own taxes (at least twenty percent of earnings no matter how little I earned,) and I was not eligible for overtime so WOW did they ever love working me long hours! So I returned to grad school thinking that would help, struggled to get all A's in my courses, and have just been informed that I may be kicked out anyway because some brainless office hen lost part of my paperwork. I did everything I was supposed to, but I'm still be punished simply for living.
I'm not saying all of this to complain but because I want you to believe me when I say I REALLY DO UNDERSTAND. And although people may try to blame us, the truth is that sometimes we can do everything in our power and it still isn't enough. We try our best to play by the rules, do everything right, be good, honest, hard-working people, and we still get shat upon by life at every turn. Even so, just know that you are not alone. There are others targeted by life in the same way you are; others who are fighting this same battle beside you. We won't stop because we know that every day we keep living is another day we spit in life's eye. The longer we can keep fighting the more we can give life and the entire world the middle-finger. We can't have success. We can't have love. We can't have a lot of things. But, fuck them all, we can still have defiance.
