I probably misunderstood "facing uncomfortable things"

[In Flux]

I've been meditating for many years, in a probably superficial way (compared to people who really dedicate themselves). Also, I've read plenty of stories (e.g. on this forum) about uncomfortable feelings coming up, and sitting with that. But I think I may have misunderstood those stories.

For me, the phrase "I feel uncomfortable with this issue" points to some kind of emotional discomfort, such as feeling nervous, anxious, scared. In my own meditation, I notice a lot of internal stress, that is connected to emotions (it feels like it could manifest itself as a scream, or as crying, though it doesn't) but the discomfort is more mental and physical. It doesn't feel emotionally uncomfortable to notice these "emotional tensions" (so to speak) but mentally uncomfortable. It's hard though to put this kind of stress into words. It's not a physical pain, it's more like a mental pressure.

Maybe this mental pressure is also something one can "just sit with". It does feel like it may subside at some point (I'm not pushing myself to much at this point, I may sit with this pressure for half an hour or a bit longer, but not much longer). Usually the start of my meditation feels more pleasant and expansive, before this tension comes up (which makes sense, first there is relaxation, then internal tension comes up).

Does this sounds familiar to anyone?
