When they were installing the alarm at my house I noticed that the main guy had nextcloud on his phone and it sparked a nice conversation about privacy. He has no technical background but managed to self-host it on his old laptop with one of those distros that have an easy UI for self-hosting (don’t remember which one exactly). He’s a pretty cool guy.
Was your whole plan about having a family in your 20s? If not, then I don’t see how the lack of a significant other matters. What career plans do you have? What interests do you have? Also, keep in mind that validation should come from within, you shouldn’t let anyone (or their absence) define how you feel about yourself.
