My 27 year old has just moved back in after splitting with his GF. DS 2 lives here also and his Gf stays most nights ( she is lovely). But my Ds's are driving me crazy, constantly bickering and fighting, lazy around the house leaving mess. Smoking weed which changes their moods and makes aggressive towards me. I have tried to sit them down and reason with them, I have ranted but nothing seems to get through. I work from home and it getting to the stage where I hate living here. I have so many other stresses too think ( dad in hospital, dementia, selling the house, money worries ) I think my had might explode.
