What maybe fine for one person may not be for another. Just because they think it is ok to get sloppy drunk once in a while doesn't mean you have to! Take care of yourself you are the only one that can, you know what drinking does to you and it isn't pretty! You might need to change a few things like where you hang out and who you hang with but it is your life you are talking about. I hated myself when I would drink and get ugly it does make one depressed and I hated that too! There is so much more to life than drinking if we just give life a chance! I don't think you will be able to get them to understand some people just don't get it, but it sounds like you do! So PLEASE just take care of you for you and for the people you choose to be around!
