It's like you read my mind and described my own parents. lol! I think perhaps...it a generational thing. My dad is like 59 and my mum's 46....my dad's life revolves around work...he can get 1-4 hours sleep a day and the rest is spent working on his ebay business. He feels if someone else is working and he's not, he's lazy and feels useless. My mum's always working too...has a pretty pitiful social life herself, to her people are not to be trusted, more to be criticized. My dad also thinks if you're not working to your grave, you have no right to be depressed about anything. (Funnily enough, he literally did work almost to his grave...he ended up getting type 1 diabetes. and was days away from dying..his fear of doctors made it ten times harder for us to get him help...I had to beg and plead with him to go to the hospital...it was me pleading with him that basically saved his life...I got no thanks whatsoever. He recognized my mum saving him...but never once ever mentioned me and how I tried to help too.)
Both my parents always tell me "what have you got to be depressed about? depression doesn't exist. you're just weak. you have such an easy, good life." When he was young he was also part of the Special Air Services and think's he's the mentally toughest guy around...but I could see through that, I saw an emotionally vulnerable and deeply insecure person. I know it stems from his abadonment as a child...like his biological mum dumped him at some friend's place when he was 3 because she couldn't look after him, and was raised by them. His foster mum was desperate for a girl but was left with this boy she wasn't fond of. So his still got rejection issues.. He also has no social life, me and my mum are basically his only social contacts. My mum has a negative outlook to everything in her life as well...and having to be around her everyday and just see her miserable, unhappy face is just damn depressing.
Before I seeked help I didn't go out of the house either, constantly anxious about everything, thinking about killing myself, irritated...how the hell couldn't they understand I needed help so bad? Once I realized I could not seek help from my parents, I had to tell my aunt one day, and she got me help, but my parents seem to still have grudges against that. They're just effing' impossible. I swear if I ever have kids, I'm never going to put them through this mental torture and feelings that you have no support.
Just know that there are others out there in the exact same shoes as you, I totally understand the pain and frustration.
