help to find someone ?

okay please don't lecture me about safety and all cause im careful okay but i need help to get more information on someone on my bbm cause they haven't been replying to me or reading the messages nor has their pms changed but my messages still send through?

i need to get hold of them because they have been helping me through a rough time lately and tbh he is like my bestfriend now , no I dont know him and no im not going to meet him but i do miss talking to him , my parents know i do it as long as im safe with what i say they let me do it cause they say im 16 now a little freedom is needed .

I only know his first name and age and bbm pin i really want to talk to him so anyone got any ideas on what to do please ?! ( no stupid answers please had bad enough week last week )
