My father (in his late 60’s) is always negative. He thinks about his regretful past, about our family, about our finances, about how our relatives might think less of him, etc. He worries about stuff he can’t control but he can’t help but think about these thoughts. Because of constant worries he’s never able to sleep well at night and his health complaints only increases. Not to mention he always complain about stuff that’s not going the way he wants it to be.
  
We try to talk him out of these negative thoughts but every time he remains thickheaded and says it’s useless and is not willing to try. 
  
I mentioned that he could try talking to a therapist about his thoughts and he rejects the idea yet again saying his worries are only his and not their business. 
  
Tbh I’m not feeling very healthy mentally myself, tho there are days where I feel a bit more optimistic but with him being so negative, it does effect me and tires me out.. I love my dad but I really don’t know how I can help him when he’s not even willing to try seeking help and shutting everyone out.. Nobody wants to keep suffering
