I think it's hilarious because I just had a moment a while back where I promised myself I would never put myself through dating someone who didn't share at least partially my love of Star Wars, Marvel, and Lord of the Rings. As long as they like and have seen one, we're okay, but I know too many people who refuse to see any outright and so much of my love of books and sci fi and fantasy comes from those franchises.
Lemme give you some... let's call it brotherly advice?
You're on the right track dude, but getting there is more than just "learning." You don't learn to love yourself, at least not in the traditional sense of learning. The easiest way I can explain it (because I was 100 percent there when I was younger and my self deprecating humor is still razor sharp) is that you begin to accept yourself.
Your biggest enemy is you, and that mentality of "If I don't like me how can someone else" is honestly the most underratedly toxic thing you can do to yourself. Because simply put, we're all stuck in our heads and we all fixate on our flaws. Of Course you're going to see yourself in a worse light than anyone else. The key is to recognize when you've been fixating on things that really aren't important.
The way out of it is different for everyone. In my case, I turned 18, started going out to bars. Not to drink, but because I started hosting an Open Mic with my friends, and to this day I play music publicly at least once a week. It sounds bad but positive validation on a hobby of yours does absolute wonders for your self esteem. 4 Years later, while I still have issues with singing on stage, I feel a whole lot better about myself than I used to because even if I think I suck, other people seem to think differently.
The other thing is that you have to hit a point where you're comfortable with yourself. Not necessarily comfortable being alone, but just comfortable with who you are. Same deal where it hits everyone differently, but this is where you need to go out and find some kind of group or place to go to.
We're our own worst enemies, every single time. I can't tell you the number of people I know who have spent months or years feeling worthless because "No one is interested, and why should they be" only for them to take a step back and work on figuring out who they are, and suddenly having a complete reversal of fortune.
The truth is, and this goes for everyone here, that people are attracted to people. You want a one night thing you can go and find it somehow, but if you're not an actual person yourself, you're not really bringing anything to the table. So rather than worrying about what kind of person you are, worry about being someone.
But then what do I know, My situation is more messed up than it's ever been. Course I wouldn't have it any other way, but that's just me being a sucker for pain.
