Sorry to hear that things did not turn out as expected for such a long time. If I may provide a suggestion... search for a serious website that is about dating (not tinder or something the like) in your area and connect to people and try to date (meet in person for at least an hour or so) at least one person once a week. Don't spend too much effort in people who just want to stick to online conversations or fooling around, just move on. If at the meetup there's no click, you have a good evening or at least you built up experience in dating. You will need to get probably seriously out of your comfort zone but it becomes easier each time! Practice makes perfect!
