Everything you describe here comes under the heading of self-harm OP, and unfortunately self-harm of this kind becomes harm to others, and living with the consequences of that makes it even harder to get out of the loop you seem to be in.
I too have a problematic relationship with alcohol in such scenarios. It takes away your filters and decision making capabilities, and makes you feel invincible, and you know full well you're not. If you have stress / unresolved issues it's a lethal combination.
The "hangover" from going through these things can end up with people never trusting you, always expecting even one sip to tip you into chaotic behaviour, and your life being dramatically curtailed and out of your own control.
You sound as if you want to be "looked after" but that can easily become being controlled and the object of weary disdain / tolerance, as it comes from a place of exasperation and fear, not from being valued.
If you want to retain agency in your life, you have to unpick the drivers behind what you're doing, and decide if the momentary and illusory satisfaction the "thrill seeking" (because that's part of it) is giving you is worth the inevitable losses and the potential pain that others around you will feel, and eventually act upon.
Deep down you know all this, you know you have to change, you have a family that you do value, but there seems to be an element of detachment from them in the way you write, which could perhaps suggest you are kicking against the constraints of adulthood in general.
You have to be honest with yourself, for all your sakes, because believe me, you don't want to end up the written off family fuck up because you didn't address your pain in a sensible manner. It can be very lonely and eating humble pie every day is a very unpleasant experience.
You've got off relatively lightly here, use the wake up call to do better for yourself and your family.
You're not a monster, you're on a dangerous path. Get off it.
All the best.
