I don't know which forum to post this in and finally decided on this one, as perhaps this is an anxiety issue? (or at least I'm hoping and praying it is!)
Yesterday I got this .. I don't know if it was a feeling (intuition?) or thought ? that I'm going to die soon; that my life is nearing it's end. Today this feeling is still sticking with me.

I just .. I guess there's just this feeling that these are my last day. Perhaps days, perhaps weeks, perhaps months. I don't know, truly, as it's a vague feeling. But it's like I should be enjoying these 'final' moments and making ammends with people in my life because I won't be around much longer.
I am not terminally ill (that I know of!

), I am only 31.. I do have depression, an anxiety disorder, OCD personality traits, and borderline personality disorder. I am HOPING and PRAYING this is OCD nonsense or something. But honestly I'm now petrified. Like WHY do I feel this way? Is this intuition?!
I guess I need to know if anyone's ever felt this way? Is this part of the disorders? I'm scared out of my mind! Is this the disorders, or my subconscious trying to tell me something?
Let me clarify: I am NOT suicidal. This is NOT a 'plan' to kill myself, I have absolutely zero desire to harm myself.
Help!
