I'm gutted - I've always had a good relationship with my daughter but lately since she's come back from a girls holiday and broke up with her boyfriend it's been drinking and partying non stop. I don't mind the teens having a drink in the house as long as it's respected but have had to have words with her lately about the increasing mess - real mess. I still have an older lad and a 16 year old at home. The older one was away on holiday and I was at my partners on sat evening when my daughter must have invited a bunch of friends back. I got a message from my older boy (who was on hols) to say I needed to get home. This was Sunday morning and my house was just trashed - no major damage but cig butts on carpet, booze everywhere, spilled etc. I was shocked as I've never seen such a mess and I just lost it and slapped her and was screaming and shouting at her. I even found boys hiding under beds. I'm a hard working single mum and if I'm not home occasionally I leave the house tidy and organised and food in etc. I actually felt a bit intimidated but it's no excuse for raising my hands. She's now left and staying at her grans. I've apologised for my over reaction but don't want her to think it's ok to treat our home like this. Advice?
