first of all, welcome to the community. thank you for taking the time to express your thoughts and concerns!
i will be very direct and blunt with you, because there is no other way to say what i am about to say.
i can really relate to your situation and am speaking from several similar experiences that were resolved successfully.
it sounds like you know what is bothering you, but feel the lack of energy to change it. also, it's very kind what you are planning for your family to get away from things, but it wont have a lasting effect unless you take some drastic action to confront the underlying problem.
our emotional state often depends on that of our family. however - when dealing with alcoholics and addicts there is an extra twist. typically, the alcoholic will drive the emotional train wreck in the family, and the family's reaction fuels the alcoholics excuse for their addiction (they all hate me, they dont understand me, etc).
the situation with your father is quite common in the united states. i have heard stats that almost one out of three people suffers from some sort of addiction.
the fact that this drains all of your energy is not surprising. addiction is a black hole for love and energy. you can put in as much caring as you want, and it will simply be consumed by the alcoholism as an excuse for more drinking until the person finds the courage to stop or suffers the consequence of their drinking (jail, death, institutions) .
the only thing that a family can do is to either decide to allow the disease to rule their life or to make the decision to put the foot down. it is not an easy decision, but there is no other decision that will send a strong enough message to the alcoholic in question.
have you ever read any literature ofor families of alcoholics? (alanon has some excellent books).
alcoholism is a family disease. by that i do not mean only that it is genetic, but that the emotional condition of the family is impacted in many ways that are not always just the alcoholics fault.
your obsession with this twilight guy is your way of escaping from your reality instead of confronting a painful subject. (just as an alcoholic escapes their demons by drinking)
you will see an interesting pattern in your family (as in most families struggling with addiction).
1. your mother escapes by pretending everything is perfect,
2. your father escapes by drinking,
3. you escape into fantasy and are set on planning another family escape (vacation).
we cannot run away from our problems. we can, but one day they catch up to us, and usually much worse.
you must all confront your problem as a family and urge your father and mother to both seek help asap. no amount of holidays or fantasies will ever cure the feeling that something is wrong here and now because THERE IS something wrong.
there is also help, and many families have gotten their lives back.
does any of this ring true?
has he ever tried to stop?
have you ever talked to any therapists about this?
thank you for taking the time to read this.
none of this is in no way meant to cause you to feel shame or guilt... on the contrary, what i write here is intended to empower you with a different point of view about your situation, at the risk of being totally wrong.
sincerely
