Multia,
I so feel your pain. It still amazes me how one's disregard for themselves effects so many around them. I would normally say to pull yourself back and let him fall but, he has already fallen which explains the bruises. The bruises from the inside are normally caused by blunt trauma. The bones and muscles impact the skin from the inside causing bruises. He may be falling and running into things, a lot. Your brother is at the point of life threating concern. I would search for any local program that may help him. There is always "Baker Act" available to you but you will incur the expense of treatment. I'm sure you will find something. The police department knows of almost every local program available. Local AA meetings are also schooled in the process. During this time it's important for you to remain strong. You are and have been doing all that you can. He is basically committing slow suicide. There should be zero quilt on your part. Keep posting, we're here for you. Prayers
