My anxiety has been through the roof lately because my chickens are sick, and besides that, some family members are going through some bad times; my brother seems to be attracted to alcohol more than he should. I feel guilty because I've been neglecting my coop in my attempts to make him recover. Now, I have to cope with more problems, and I'm so anxious and nervous. Do interventions work in such cases? Should I try to help him, or should I let him figure this out on his own? I am also looking for a piece of advice and some encouragement.
I’m sorry for what you’re going through, I can’t say wether intervention works or not unfortunatly, from what I do know about those who suffer from substance abuse, some do it is a coping mechanism and for that they’ll probably need therapy to help them work through it, for others, it can be just who they are or because they have a mental illness and as hard as it is to accept you can’t help them, no one really can. You have to cut them loose or they will drag you down with them wether they intend to or not.
You have anxiety over this so I know you’re a very empathetic person, but that means that you’re also an easy victim to take advantage of, I don’t know anything about what kind of person your brother is, but if he can’t make the choice to help himself no one else can, and anyone who makes it their life’s mission to save those who ultimately don’t want to save themselves just go down with that ship with them.
I’m speaking from the knowledge of what I’ve witnessed with my own family, my aunt’s husband drank himself to death, no one, not even his wife or children, his church and councilors, could stop him. My great aunt and uncle lost their home, job, and retirement because they gave up everything to put their son through rehab multiple times.
My parents haven’t learned from those lessons and have already blown through their savings, retirement, and are likely going to lose their home and job because they can’t say no and can’t stop supporting my narcissistic psychopathic brother.
My parents, my great aunt and uncle, and my aunt never got a thank you from the people they’ve destroyed their lives trying to help.
The fact that what your brother is going through is already impacting you this much shows that
you are suffering from this, and by association so is your flock. I know you care about your brother but all you can do is encourage him to change his life, but ultimately you need to look out for your own well being because he won’t.
Please be kind to yourself, this isn’t your fault, but you need to be your own advocate and surround yourself with people that will also have your back.
interventions only work if the person recognizes the problem, otherwise you may be enabling the behavior. I have a sibling that OD'd three times and now yes abusing alcohol and drugs, another that is abusing alcohol. I'm there for them as a positive presence and am ready to help them when they recognize that they have a problem.
