My dad is a pathological liar..?

your dad sounds confused.maybe you guys should set up some rules as there seems to be no clear boundary .If he starts on you then i guss you could try and blank him maybe write him a letter explaining how you feel and maybe talk to your mum sometimes talkig to people that are sick is hard and maybe you need some family intervention as he isnt caring for you to the best of his ability or you could say his medication is effecting hs abillity he may need time out too if he has depression depression can bring on all sorts of odd and confusing behavior r .parents have alot to deal with and when it gets too much they try and control everything by being to hard .......you could go see a dr about his behavior if it is effecting the home life you can get someone to asses him ...............if he cant cope he may need some help good luck flower xx btw hes not being a proper dad to your siblings if they are also liviing n a house where there is daily conflict it effects them too in different ways
