Focus on your health. Don't compare yourself to your friends as hard as it is and as much as it seems like you need to pace your life according to the way they live theirs. Focus on your work because that's what gets bills paid and what helps you take care of your needs. I can assure you that youre better off not having someone there just because thats what society calls normal or because it looks right. And I'm not trying to put any negativity on your friends marriages but there is no guarantee that theyre going to last and that's a headache all in and of itself. I'm only trying to show that what looks like paradise on the outside can be full of hell on the inside. Appreciate your life and your choices and your goals and the girl for you will come alone when you least expect. However, you have to remain open and the best way to do that is to give yourself permission to live differently than other people and not feel like youre missing out just because someone takes a step that you dont take. Know that theres someone looking at you and wishing they had your life because they think its filled with ease and satisfaction. If they only knew, right?
Maybe curious? Young ignorant naive people can be curious.
No reason to feel so at 24!
