will it ever make any sense?

I haven't been on here in a while again.  My anxiety has been pretty low overall.  Yesterday and today I am having anxiety again and I have no idea why, as usual.  After all these years I feel like there should be some kind of an answer to be found.  I can understand it when there are recognizable triggers or when stress is high but I cannot understand it when it hits me out of the blue when everything is just fine.  Suck it up and keep breathing through it.
