I spent most of the time
to working at thea restaurant
("restaurant" is not definite so you must use "a")
waswere a few things to worry abouttake care of
("worry about" doesn't make much sense in this sentence)
I was kind of worried
--> "kind of" is spoken language so I don't think you should use it in a piece of writing.
gotbought two jeans and three t-shirts .
--> again, "got" is quite colloquial, so you should use "bought" instead.
It'sIt was even harder to find
--> you are writing about something in the past, so use past tense in all your sentences.
You should really work on your grammar if you want to improve your writing.Best
