need advice urgently

hi im not exactly sure how to put this so that it makes sense without going into to much detail but the last couple of months i have had a problem with my mental state that i havent had for almost 10 years and the hardest thing about is that last time i delt with it on my own and managed to supress this problem but its back and i just cant seem to do what i did last time and im worried about the ppl around me finding out as i dont exactly want them to know. it doesnt affect my abilty to do day to day stuff at least not yet and i dont feel like im in harms way but i really want to be able to make it go away
