Guns and other potentially dangerous objects

Hi. I'm bipolar II, with a family history of bipolar I and II, along with a couple of suicides by gun.

A couple of years ago, when my shrink learned that I collect and use firearms for hunting, shooting, and self-defense, he began demanding that I get rid of them. I refused. We had a long argument. He lost -- but wasn't happy about it, and isn't to this day. Personally, I think he has control issues: we both want to be in control of MY life.

I think I have good reasons:

1. I've never attempted suicide, just thought about it a few times. If I ever did attempt it, I wouldn't use a gun. I grew up seeing the effect on my mother of finding her father right after he shot himself.

2. If I have to get rid of the guns, then logic says I should have to do the same with every other potentially dangerous object. Goodbye to all the kitchen knives, household chemicals, prescription meds, car keys, etc., etc. What about my hiking boots, in case I decide to walk up a mountain and jump? They'd have to lock me in a dark closet without my belt or shoe-laces. Who wants to live like that?

3. There is nowhere else more secure to keep my guns than in my locked safe. (Except for a couple that I keep loaded and available for home and personal defense.)

4. When I was young, I knew of two incidents (one involving my mother) in which tragedy was avoided only because of guns which never had to be fired, but were used to scare off intruders. Nothing is more likely to drive me into a suicidal rage and despair than becoming the helpless victim of a violent crime, or watching my wife become one, if the intruder doesn't actually kill us during the experience. I KNOW this because I was once mugged and beaten by four guys on a street.

However. . . I also know I'm capable at times of irrational thinking. Am I being irrational about this issue?
