Stressed out about something

I am sorry for making another thread but something is really really stressing me out and idk what to do and i know people cant give specific advise but it might be good to hear what others might do in the situation.

some things have been getting more intense for me over the last few months and it is now very distracting but not only because the stuff is distracting but because i am very scared of the consequences of people finding out so it is literally making me panic over the posibility that i will 'get caught' i am even having nightmares about it and the stress is keeping me up at night. but i have good reason to be stressed about people finding out because last time it did not end well at all. but i also cant ignore the stuff that is happening and i cant talk about it properly either and i just want to not be so stressed.

if you were in a situation where you believed in something that others dont and wont but you still do and because of that you cannot tell other people about the things you believe what would you do? also at the same time in the past when you have gone against your better judgment and told supports about such things it has only caused bad horrible terrible things to happen and would likely do the same if those supports found out again. what would you do? if supports finding out would likely ruin your future would you keep hiding it so long as it wasnt hurting you?

i am sorry this is very cryptic although if i am honest even if i explained it properly i still doubt it would make sense fully to others.
