Yes, friends tend to listen to one another and try to empathize. Yet, they cannot "fix" each other. We are here to help each other through the tough times and to celebrate the good times.
Often times, difficulties with allowing people to become closer to us has a lot to do with our self-esteem. We may be concerned about what others may see if they get closer to us.
I hope you can work on this with the help of a therapist. It can be very painful to feel distant from everyone.
