I'm 39 and really wish I was there. Things have certainly improved but I'm (still) single, never married, no kids (not sure if I want them but I won't be the one to take it off the table if marriage even happens), and only a couple of dead-end relationships. Given my great career and everything that affords, I can at least tell my younger self that money absolutely does not buy happiness, and maybe I could tell my younger self that certain traumas don't mean I have to afraid of people, don't be afraid of rejection, and don't let clearly bad people hurt and take advantage of you (me), maybe I'd have spent less time focused on building a career and more time trying to build social and dating skill.

In short, I don't know if I can tell my younger self things will be better in some regards, but I would at least tell my younger self that, despite how much time has gone by, I still have hope. I would also tell myself it's absolutely okay to not get with people who are unattractive to me, especially when they are clearly abusive and manipulative.

C'est la vie, je suppose.
