I can't say I've ever thought that way, but it's probably mostly harmless if it helps in difficult times.

That said, reincarnation is not a guarantee, so in my opinion, try to learn to make the most of what you do have or can have now, it's the only life you know you've got for sure, don't lose sight of that on a dream that it might be better next time.

Or, as a bad analogy, don't spend all your savings on lotto tickets, hoping you'll win big one day, since it will probably never happen.

Also, hugs, and sorry to hear you're struggling a bit right now, this stuff can be really hard, for sure.
