Sudden rush of feeling which is uncontrollable

Hi, I am feeling a sudden fear these days..every time I meet people I make sure to sanitize myself and my surroundings as well.. but there are these sudden fear whenever I have to go out for any work that what if I bringing back home the disease with me? What if my oarents get that from me? What if I cant handel all these? What will I do if I make them suffer beccause of me? Will I be able to handle the fact that I was the reason they might be suffering or are they suffesring right now?? I dont know why these things come into my mind and just make a room and dont leave even if I try harder... At this point whatever I do all these things poke me in my mind that am I allowed to be smiling or am I allowed to be normal when I might be the reason for my loved ones pain... ...these are rhe thoughts running in my mind for last i dont know how much days... So just thought of taking the courage and put it in words...
