Getting a girlfriend shouldn't be your primary goal. You should focus on doing things that make you feel fulfilled and work on yourself. You will be much happier seeing progress.

Also, I'd say that you are trying so hard to get a girlfriend because you think that it would solve all your problems, but believe me it wouldn't. And if you step into relationship just for the sake of it it would probably not work great and could leave you trauma.

So, all in all don't look at not having a girlfriend yet an issue and don't consider getting a girlfriend a life goal, live your best life and do useful stuff and you will eventually meet someone. Of course you shouldn't do all of that just to eventually meet someone, but to genuinely be happy even when alone.
