Life doesn't sort itself out automatically. It takes, well, a lifetime. You sound like someone who's probably got - and possibly has always had - heightened perceptive abilities and sensitivity, and notice a lot more than the average person. Whether you like guys or girls is irrelevant. It sounds like you are into both. Me too. It's cool. More options.
Living alone is alright. Prior to meeting my fiancee I was single and celibate for four years, by choice. It was amazing. I got a lonely a time or two but that loneliness was easily filled by self care, hanging out with friends, doing things I enjoyed, and just getting to know myself. It sounds like you're sorting out a lot of things about yourself and feel conflicted about a lot of stuff. Don't rush it. Just enjoy the process. You only get to be young once. You only get to be any age once. One day at a time.
