Should i keep writing it& what do you think of it?

I think that your story is well-written and intriguing. You are obviously literate with a knowledge of how to format your story correctly! And, you have chosen to write in the present tense (which is more difficult than writing in past tense) without slipping into past tense as often happens with (inexperienced) writers -- the only error I saw was when you wrote: I hung up, where you should have written: I hang up. I am wondering, though, whether Tina and Alex are "your" parents in the story and would suggest that you explain at some point exactly who they are. You might write: I call my parents familiarly by their first names (if that's the case). Anyway, I think that you have a great beginning and a talent for writing and that you should definitely continue developing the story -- particularly if you have your plot well planned; in my opinion, your story has potential. Good luck!
