it goes like this: the word, comma, the space between words and then the next word same works with the dot I need to _choose_, because _choice_ is a noun

During my last year of high school, I hit rock bottom. I needed to choose which college I wanted to study at. I was going to apply to a police academy but they hire based upon good academic subject test grades, and I'm not real good at studying. Needless to say, I failed to get in. Then I decided to choose a random college even though I knew it was a horrible option. I admit I felt some regret afterwards. But now I found something that I'm really interested in and is enjoyable to me. Hope this helps :)

I had hit rock bottom, in the last year of my senior high, when I needed to choose which college I wanted to study at. I remember that year I was going to apply to a police academy but they are only interested in the academic subject test results. I’m not good at studying, so unfortunately, I failed. Then I chose a college at random. I know it’s a bad option, and afterwards I felt a little regret, but now I have found something that interests me, and is enjoyable. Is there anyone who can help me to correct my writing ? You are welcome to ask me for explanation of the changes I have made - either in a reply here or by sending me a message.
