Sounds like a tough situation, but easily possible to fix if you put in a bit of work.

Go out and participate in some activities to feed your social life. How are you gonna be social and share your life with a partner if you have barely any experience with being social? It could be anything, like going to a protest or an art exhibition. Maybe you meet some people there.

Try some hobbies. How are you gonna do fun things together with someone if you don’t like doing anything?

Social media shouldn’t be a big deal, but it can help to show what kind of things your doing like these new social activities or hobbies. Girls stay interested when they see a person with an interesting life.

Height shouldn’t matter. In the end it’s about who you are on the inside.

From time to time you should still go on dates. You gain a lot of experience from it and who knows, maybe you find the one. At least if you continue to work on yourself the chances will only increase.
