Feeling so envious

Ever since highschool, i feel so envious especially to my friends for having a complete family. Even though they're financially unstable, they were still happy the fact that they have complete family makes me feel so envious. Its not that i want my mom and dad to get back together, i know there'll be no chance ever since my dad owe my mom so big and they never have a proper conversation since then. My mom also found someone so i don't really wanna push her to my dad, though i think dad still in love with mom its his fault for not being a good person when he still have her. I don't really want them back together, its just that felt so envious seeing my friends having a happy and complete family, there was a time i said I'd rather be financially unstable but still have a complete family. I cried a while ago feeling so envious to my friends thinking i don't have someone i relate to.
