Am I the @sshole?

I just had an argument with my dad over what time we should head home. He wanted to wait until at least 6:30 before we make the trek back to the house, which is another hour. His reasoning was that we would avoid rush hour traffic that way. My thing was that it wouldn't make a damn bit of difference on the time taken, and that I need my pre-meal insulin soon. He asked me why I couldn't just take my insulin right away, and then go home to eat. (Which would put my life at risk from low blood sugar, btw.) I ended up yelling and screaming at him, because it is no exaggeration to say I've explained this hundreds of times. He said I could just eat something on the road. I responded that would require me to tell Mom not to bother making dinner, and he said I didn't have to have a full meal with my insulin. (Which, yes. Yes, I do.) I finally got so frustrated that I took my Admelog (pre-meal insulin) out of the thermos, rolled down the van window, and threw it down on the ground, smashing the vial.

You're 46.., arguing with your dad about taking insulin and who eats what and when ?

I'm tempted to tell you to grow up but that would be counterproductive, I think.

No matter how the situation played out, you could have just not eaten the meal your mom made or could have called your mom and told her not to cook.

Throwing a temper tantrum and smashing what amounts to a costly vial of medication is just simply childish....

@HikingMan

How old are you again ?
47, I think you said....

And yet when Dad sets his mind on something, that is that. It doesn't help that he's also kinda my boss.

Seems to me that a 47 year old could be mature, respectful, and still do his own thing in his own way without arguing over it and smashing a vial of medication that's fairly expensive ?

You'd think, right?

As long as you seem happy with the way things are I guess there's no point in trying to explain anything.

I wouldn't be asking for feedback if I was happy with the way things went. For all the abusive and hostile words I have for others, I reserve the worst to punish myself after I do stupid shit like

smashing a vial of medication that's fairly expensive

@LordShadowfire Only you can change your direct circumstances.
Only you can change the ways you react to certain things that displease you.
In this instance, you failed to handle things in a mature manner.

You should have taken your pre-meal, then ate something, and then said you were full when you got home....

I struggle to understand how that would have been some earth ending tragedy in any sense ?
