Do I have COVID 19 ?

So recently my mom has had a plain of and on fever for a week, she says she has body aches, and feels thirsty and obvious feeling of unwellness, she tested a few days ago for COVID and got positive supposedly, my father being the closest one of contact with her (as they sleep In the same room etc) tested the same day as my mother, but my father got a negative result, he has no symptoms, my sister and I tested at the time of this question, this morning, her and I r symptomless both of us don’t have any medical issues and such as well I just feel generally exhausted for the simple fact of working 9 hours shifts at my job without a day off in over a week, I tend to have sick phobias and had a bit of a panic attack last night when I heard of my mother’s results, for now I’m anxious to know what my results are and if I should even go to work or worse yet tell my fiancé who has asthma that she can’t come see me at all for a certain amount of time until I know if or if not I have anything, how do I calm down knowing the fact that I might have something that can potentially Kill me Or worse yet god forbid harm someone I love and care about
