Looking for Professional Mentor

No networking. Non target. Non Diversity. Intelligent, strong fin modelling, winner of several competitions at national level, full package for traditional high finance, etc. Struck out in recruiting after applying to 500 roles and only hearing back from one. Secured the offer from that one place with nothing else in my hands. Interned at BB in MO/BO role. Told supervisors that work was easy and experience could be better if I did something more Fin Statement oriented. Performed well in tasks and asked for more work. Started doing analyst and not intern work and after singlehandedly doing work my boss was supposed to do, begged supervisor to move me. Got moved to a different group because of persistent asking over first few weeks of internship and performance. Was still in MO/BO but role was client facing and was a revenue generator. Group had a lot of interaction with ER and IB. Was tasked with supporting a team where 2 of the 3 analysts had taken time off. Got hit with heavy work but blew everyone away with Fin Modeling skills and analysis. Received praise after praise. Expressed interest in moving to different role again. Managed to take the FT IB and Corp Banking training with incoming FT analysts. Absolutely leveled the FT people in all aspects. My deliverable/homework was perfect. Someone took notice of me. Was interviewed for several high finance jobs within same city and bank. Received FT offer from original intern group, group I was moved to, and top IB group that expressed interest in me. Chose the IB team.

I have never had a mentor and am looking for someone to help me in the industry. I have worked my ass off to get where I am and I have never spoken with anyone about how I did it or what my next steps are. Spent entire Sophomore year not sleeping and being a teenager because I was learning everything I could from the internet and books. No one from my school is in IB, we have 0 alumni, only teachers know what it is, and I feel so alone. I am just looking for a friend and a voice to talk to. Preferably someone who I can connect with on LinkedIn and text/call once in a while for help.
