Is it normal to think this much at times?

Is it normal to think that everyone out in public knows what your thinking and how you feel even if you aint sure yourself?I have been suffering anxiety and depression for the past few months but am slowly getting better but still have trouble with i guess a social thing as when i am around ppl i dont know i always worry that they know what im thinking or what is going on with me, i mena i have had some pretty morbid thoughts due to the depression but im not a weird person so to speak? Is there a way of stopping myself from worrying so much?
