Getting zero encouragement or positive feedback from my boss is really killing me from the inside. There isn't even a negative feedback. There's absolutely nothing.
PhD is such a lonely path as it is, and being ignored by your advisor is just...soul-crushing.
I did a collaboration with my friend from another lab, and even though her lab is bigger and crazier than ours, her professor found the time to compliment our work and even told us he will present it in a presentation he gives in Meta. Really, it's not that hard to say a kind word here and there.

Academics suck out the soul from many people. Only a couple precent of phd papers are actually even useful in the real world...

Hmm... Boss that keeps away and let you do your thing... Things could be worse.

@2Fdev2Ftcsh No, not really. My research plan was drafted by him, and I have a timeline with deliverables. So I have to research according to his interests and his time estimations, but without any guidance other than a 2 page project sheet.

@NickyBones Yeah, I get it. Some supervisors are like that unfortunately - mine could be *sometimes*, but was mostly pretty good so I can't really complain. Others though I knew basically quit because of their supervisors being rubbish. It's a bit of a one-sided power dynamic that doesn't have an easy solution.

Do you have a wider supervisory panel, as well as your supervisor? (Certainly in the UK that's the norm.) If this is the case then maybe going to one of them for general advice, as well as project specific advice would be worth doing. Far better doing that than burning out or getting super demotivated because your supervisor is just being unreasonably uninterested in your work.
