I do agree it's hard to foster new relationships. New people I meet in my high phases end up liking my company and I hang out more, like meet up for lunches and dinners, go watch a play or a comedy show together etc. Am more helpful and am generally around when they need me, like giving a helping hand when they are moving homes etc.

In my down phase I am withdrawn, completely avoid meeting people as much as I can, and usually, call in sick or find some other reason to avoid meeting anyone.

That leaves people very confused, and that I am not a consistent with my behavior.

It sucks really.
