when does the frontal lobe develop?

I desperately need my frontal lobe to develop. I am 20 years old. (21 in September) and there are things I wanna do and not regret -- like get tattoos and learn to drive and commit to learning how to drive (I'M FROM THE UK AND IT'S NORMAL NOT TO DRIVE AT 20!!!!!!) and also go to Uni or get an actual real job. I am sick of my child brain, I'm not a child anymore.

I've been going to the gym for over a month now and I can actually see progress which is INSAAANE and doing wonders for my confidence. I am butching out so hard this year, it's my biggest New Years Resolution.

It is also in my plans to come out to my broader family this year. Sick of showing up to family functions every 8 months and feeling like there's an elephant in the room. There is still a tiny part of my brain (resulting from growing up in a heteronormative society) that says "what if one day you realise you love men and want to marry a man and you're a big liar and you have to tell everyone how wrong you were?" but that's so stupid and never going to happen.

Had a dream about my ex-highschool-situationship (we were homoerotic friends) lastnight and it was ROUGH and that's all I wish to say about that.

MAN! I wish I had some lesbian friends on here. 

That's all, void.

See you next time.
