How far can you go alone + Where should I be at right now?

hey reddit; this is pretty much my first outreach to any outside source tbh. I'm a 15 year old aspiring rap artist out of maryland. i started just about 2 months ago. i have pretty much worked alone relentlessly with simply a pen and pad and iPhone for practicing over beats and studying other lyricists/poets/rappers and i'm definantly making good progress. but i started recently thinking, when should i come out of this little shell. I pretty much cut off alot of my friends and social life to devote every spare second to this, but I have a feeling that although its a good practice of discipline, it may not be correct. I'm not complaining about giving rapping my all my free time.. but how far can one person go alone, hypothetically? And where should I even start? I cant drive for another .5-1 years, and even then I live in the suburbs where there are like 10 black kids at my school besides me and noone appreciates lyricism or even hip hop, so I feel like I have so little people to reach out to or to partner with. i just feel like noone can relate to my ambition and i guess i need tips on how to cope with that and for how long..

ontop of that, i need a reality check. where should a 15 year old aspiring artist who's been crafting for 2-3 months be? What should I be occupying myself with, what equipment should i be playing with, should i be assembling projects already, all the details. i understand that's a very general question, i apologize in advance; but I am working my damn hardest to always be ahead of the expectations, especially lyrically.. and I want to know whether I should be studying or practicing more, or if I am approaching the whole thing wrong.

Sorry for the lengthiness, and the oddly formatted questions. I have so much more to say than this but I guess these are my two main concerns. Like I said I never reached out to anyone about my hip hop endeavors but i fucks with yall heavy if you can help me out here. been sittin in the dark for a minute.
