You need to get rid of all these thoughts - I do things alone all the time. So do many people. That doesn't make you lame at all. You should go on a vacation somewhere else in the world. Stay at a hostel and make friends with other people staying there. Go climb a mountain or do something that takes you out of your comfort zone. Learn a new language instead of playing a game. Join a meetup related to something you enjoy. Take a hike. Go hunting. Eat or cook some food that you never thought you'd try. There's a million interesting things to do, and you're wasting each day alone and boring. Don't do that. You can literally stop right now.
Then google how to make small talk. Most of it has to do with asking some basic questions, actively listening, and asking new questions based on what the other person has said. It's a skill that needs to be practiced, so NOT doing it ain't helping you at all. Seriously, if you want to be more interesting, you HAVE to put yourself out there. It's not just going to happen. Also, since you have nothing going on, you have nothing to talk about. Change this.
So if you're serious about wanting to go on dates, you're going to need to start at square 1. Stop being boring. You can do it - you just have to start.
