Help, Will you pray for me to deal with my anger (bitterness)?

Help, I am struggling. I pray for these people and yet there is a part of me that wants to smack them and say, "GET A CLUE" . I am a christian, and I love God and let him love me to the best of my ability. I am well known in my church and many people want to talk to me, whether is it to share something or chat. I love people, so this to me is easy to do, however, there are a few people that feel the need to come and admonish me because I am talking to or listening to someone i am not supposed to. I mean they throw scripture at me in condemnation and when I refuse to agree with their 'truth" they say I am abusing them or can't hear truth. I dont recall God saying you could and could not talk to people, especially in faith. Generally the people that approach me want to be affirmed, approved, accepted just plain loved. I have a hard time beleiving that such a loving God would want us to cast the people away that are struggling
