I am also the oldest in my family, Adrian. I had two younger brothers. One now, and he hates me more than probably anyone else alive. I know how it feels to be seen to be the one who has to guide others. But you can't do that when you don't even know who you are and what you want. I ran away to sea when I was a little younger than you, just to get away from everything. I was told, in no uncertain terms, to not come back, lol. By my mom.
It will be okay. You're at the point where you get to decide who you want to be. You don't have to be a cut out of who the world wants you to be, okay? I mean the fact that you're here is kind of proof that you're not. You're Adrian. Wry, smart, erudite, determined, open, gentle, and cooks a mean steak.

Hold on to that. Find things you want to do and do them, hon. Find what you like, and live like there's no tomorrow.
I am proud of you and I believe in you. Go out there and find who you are and what you want, okay? Don't let anyone guilt you into living their life for them.
