I would think it is ok as long as you arent paying for the sessions while you are helping him/her out. Only thing is, in therapy the client and the therapist are not supposed to be in a dual... uhh i forget the exact word but its like you are not supposed to have a dual relationship. Eg You(client)and him(therapist) PLUS him(client) and you(medical stuff). Same reason as why they dont allow therapists and clients to have friendships out of the session. Its a dual relationship. I really wish I could think of that word.
