Hey, Theexcitingkid. I am very glad that you came here. There is no judgement, just many people who have also been in some very sad, painful, confusing, difficult places and want to listen and to help. I'm so sorry about your mom's illness and what happened to your sister. Life can throw some horrible things at us, but it gets better, and your mom and your sister need your help.
Please get some sleep, don't drink anymore tonight and come back tomorrow. We care. Sending you love and hugs.
