^ I agree. Venting can be great--it releases pressure exactly like the word implies. Letting out a little steam is very healthy. It can stop an explosion!

If you feel like you are venting too much to others and you don't want to drive them away, just vent in another way, like through writing out your thoughts, using poetry, artwork, music, prayer, a punching bag, something that lets you get the negative feelings out but that doesn't necessarily involve talking to another person (because most of us have probably been guilty of complaining too much and then another person got tired of it and then they didn't react so well).
