@Marlee29,
You don't really "make" friends. You start with casual contact and allow the connections to develop naturally. Some will be receptive to this and some won't.
You say you come off strong, so you are aware that you have a strong personality. I am a pretty reserved person, type B personality, and my best friend is about as type A as you can get. I don't think your strong personality is your problem. I think you may just be trying too hard. Relax a little when you encounter someone new or even when you are with a casual acquaintance. Be friendly, honest, empathetic, and care.
