I dont know if this is your reason, but it was the reason with me when i was repressing how i felt and my emotions. I didnt want to show my family/friends how i felt because i did not want to be a burden or nuisance by making my worries the worries of people i loved.Looking back on it now, all i can say is that i regret doing this. You friends and family love you, and they are there for you :)Again, i dont know if this is your situation, but if it is, i hope my advice helps ^^ you can PM me if you wish to talk more ^^
