Depends on:

- If it is something you need to do but somehow you play an imaginary scenario in you head and that’s creating this disturbing feeling.

- It’s not something you need (or can) act on it but you afraid of something. Like a sickness that bot happened, an accident or stuff like that.

- It might be something that you or someone you care go through a difficult time and that feeling of uncertainty can create this

Etc…

I am not sure if there can be a blanket advice about any of it but starting talking about it or posting a note on Nostr to start a collective discussion about it seems like a good starting point :))
