Question What are the most frustrating things about weightlessness?

What are the most frustrating things in weightlessness ie. things that are so simple and easy on earth but just seem almost impossible to do in space?

One the the most confronting features of the weightlessness is human body and mind functioning itself.
Human is the best known creature to adapt to new environment, so with training and imagination we might find them having fun eating, playing ball, etc.
Weightlessness even contributed to commercial successes like Space pen and findings like 'bizarre' behavior of rotating objects flip.

Additionally.

1. There are also indications that ‘outer space’ humans on might gain a mutation that raises their survival advantage.

2. If coming to Earth there neurology aspects.
Children are born with exact parameters to interact with Earth gravity in a healthy way.

Looks like to be extraterrestrial born makes one alien for Earth (except a short artificial gravity adaptation - and back).

Which Way Is Up? Neurons That Infer Direction of Gravity Discovered - Neuroscience News (https://neurosciencenews.com/gravity-visual-cortex-neurons-3818/)

- People are intuitive physicists, knowing from birth how objects under the influence of gravity are likely to fall, topple or roll. In a new study, scientists have found the brain cells apparently responsible for this innate wisdom.*

- In a part of the brain responsible for recognizing color, texture and shape, Johns Hopkins University researchers found neurons that used large-scale environmental cues to infer the direction of gravity. The findings, forthcoming this month in the journal Current Biology, and just posted online, suggest these cells help humans orient themselves and predict how objects will behave.

I think it would be frustrating and disgusting to have diarrhea in weightless space.
Vomiting is also bad.
Imagine if in a Helmet space walking.

One of the more frustrations would be your hand inches away from something to hold onto and finding it difficult to get there with nothing to push or pull against, then drifting away.

The Japanese experimented with little fan packs to get around with in a capsule. When they were on the ISS. I don't know how that worked out.
But hey it was a good idea, the fans were activated with hold down button on them. So they wouldn't get carried away with it. A little push here and there.

BONE ATROPHY. It is the worst thing ever. Bone Atrophy decreases bone density and if it goes far enough you will have to have supports when you come back to earth.

One of them would probably be the inability to shower. Astronauts use wet wipes to clean themselves off which, yeah, that works, but it just can't really feel the same.
