I stole a suicide hotline phone number for personal uses

When I was 13 I called my local mental health hotline for help because I was feeling suicidal. The guy I talked to was very nice and caring and gave me his personal phone number so I could reach him anytime I was feeling that way and needed someone to talk to. Not too long after I got a new phone and lost his number. I called hotline again hoping to get the same man and he is. I told him I lost his number so he gave me a new one saying he changed his number. I lose the new number. I call hotline hoping to get the same guy and he is. He is surprised to see me again (he has a hard time remembering names) and I explain losing his number again. So he gives me another new number and assures me that it is the last one. I lose that number, call hotline and get him. I tell him I am sorry but I lost the number he gave me and he is very confused so I admit it is my third time calling and losing his number. He is shocked and says he thought he had given it to his girlfriend and that is why he couldn't call or text her.
