Sharon:
I see that you are terribly overwhelmed and I feel for you. Now, I don't know if your last post was just a 'venting' or not, but you've laid some pretty difficult situations out that you seem to have no idea how to begin to solve. Your coming to these forums shows you that you have the support of other people. I do not mean for this to be agressive sounding, but you've been given tools and resources - it's time to take
some action.
I find I am using alcohol to cope with the depression I feel and the worries about mum,
Using alcohol as a 'coping' tool doesn't work, period. If you're 'coping' with something, you're actively handling it and moving that situation to a point of resolution. Alcohol will not help you find any answers to any of your problems, so don't look for resolution there. Don't allow yourself to 'need' alcohol to handle the struggles you are faced with now, otherwise you might just be trading off one struggle for the next.
luckly my mum doesn't know as if she did she would be really upset so I keep it from her and also from my few friends
I don't think that 'luckily' is a good description of this situation. One of
my struggles led me to deceive people that make my life worth living. I can tell you, flat out - no sugar coating, if you're hiding your alcohol use (for any reason at all!), it already
is a problem. Recognize that and work toward changing it - you won't be able to work on those things around you if you aren't willing to work on yourself.
You can't control your dad or your brother or your mom's cancer. You
can control yourself. I'm deeply touched by your challenges as they seem to tap into the most fundamental parts of you; and you need to equip yourself with the tools necessary to meet these challenges. But, you won't be able to find and use the right tools if you're busy using the wrong ones. Make change happen in your life, be active in that! If you find yourself slipping into draining, useless routines, actively do something different. Hum a song, take a walk, read a book, find something funny about it all (reminds me of a comment
Blue posted), make a new friend, help a child at a playground, plant a flower, feed the birds in a park, crochet something, do a crossword puzzle, crayons & a coloring book!, volunteer at a shelter. Actively go outside or deep within yourself and refuse the old tool while intently finding a new one.
I'm praying for you, luv.
