How important is intimacy in general for overall well-being and health?

I’ve been chatting with chatGPT for a while on this and per usual the answers are very ambiguous. It’s always something like; ‘ that depends from person to person, it can have consequences on health bla bla bla ‘

Like I need more concrete answers. What happens when a person lacks intimacy? What exactly does that include? What’s the minimum, like when can you say it’s not healthy? What amount do we actually need it in?

My mom tells me she’s doing fine, but it seems to me, that she goes to work, and then gets home, watch TV with the cat and go to work next day. Eventually she will go to visit my grandparents and in very limited periods she hangs out with the few friends she has, but she will go through many months of just not seeing anyone. She never mentions talking about emotions and quite frankly it doesn’t seem like she has a lively inner life, not that she’s not smart, she’s obviously not as emotional as me. I just see her light up in social situations, like it seems like she really needs it, but it’s difficult to confront her, partly because I don’t truly know and she gets really defensive about it, if I just ask out of curiosity. I can tell I’ve become a bit like her, which I don’t like, but I can’t be bothered with people either. It just kind of sucks and I wish I had some better role models, to kind of get me out of my shell.

Obviously, I’m really lonely, and I wouldn’t know who to call, in a situation where I’d lost everything. I probably would just go alone with that and suppress it, like I do already and it’s not healthy.

So anyway, that’s the reason I’m asking, but the original question stands as, where does the line go? And Id love some more concrete answers than: ‘ it depends ‘, if anyone can.
