Costly Mistakes

I was looking over the essays I submitted, and I realize that I made 2 grammar mistakes!!! The 1st one maybe a bit hard to notice, but the second one is glaring I think. Ahh, this is surely gonna cost me. I feel like screaming!! I am gonna look like an idiot. Costly mistakes. A lousy day.
I spent 1/2 hour clutching my stomach, sitting at chinese food restaurant in the top floor of the mall after a relative sent me there to buy her dinner and my stomach ulcer started to attack just then. And then I spent an hour buying her grocery supply. Then went to the pharmacy for her to get her diabetic meds. And I waited for the bus for 45 minutes. And another 1/2 hour to walk down from the bus stop. The day could not end sooner. Lousy public transport in my town.
Making mistakes in essays is really suicidal. What a way to kill the initial perceptions of u in the college eyes. All the efforts I put into getting my paper work done are wasted. I went to 3 schools altogether, so lot of transcripts involved. And money is wasted. College applications are costly processes.

I have to focus on what is most important to me right now, getting into college. Nothing else should matter, I have to tell myself. Do not let people's judgmental views get to you. What they know how much in life I went through. Sometimes, I feel like I have lived a long and dreary life. What, so many years I have to go through still? I have never shared all the more details that went through my life in the long past here. Too much happened long before, tiring, hateful. It has been a long journey. We live in a petty, dark, vengeful and backstabbing world. That is the wisdom I gained through the years. It is a dog eat dog world.
