i agree with Cyrano... sometimes stuff builds up, a thing that happened in the past could only now be pressuring to the surface... combined with other events, not processed completely, and one morning you wake up feeling strangely but there seems to be no logical explanation...

with help you can sort through the dark waves and get to the center... someone like a therapist can better help you find out more exactly what it is...

but you're more than welcome to seek advice here as well.. a lot of us understand... don't isolate... reach out.. there are real good people available and they care...
