Hi, I Have A Purple Tinted Bump That When I

Hi, I have a purple tinted bump that when I push down it feels as if there's a harder pea sized ball underneath the skin, it's on the rim of my anus, my anus has also turned a dark purple in color around the rim, I'm young and afraid to tell anyone or go a doctor, I think it's a hemorrhoid and I'm not sure what to do!
