why?

I can't explain it but I feel so low.  Sure I guess one would say that I would have reason to feel down based on what I've been through -but - why now?  Although T is not doing well in school (horrible, in fact) he's been great here at home.  Then why I am feeling so yucky?  It's more about the emotions.....I have no energy to speak of.  I took a nap sitting up yesterday before going off to an Al Anon meeting and then this morning - I slept in (T didn't go to school in the AM) and now I am still exhausted.  I have so much to do but I just can't do it.  Maybe I'm coming down with something, too.  Who knows?  I know part of the reason is I have nothing to be excited about.  I have no job and no desire to look right now - at the same time.  Just in rut that I need to get out of.  I know I've done exactly what I should not have done - I put far too much energy into T.  I know better and yet I let it happen.  Intellectually, I know that.  Emotionally -  I let it get the best of me.   Even soccer doesn't do it.  Our game is scheduled for 11PM tonight.  And I think I'm tired now?   This could be just a temporary situation and I'll give it some time.  If it continues......I must do something about it.  Perhaps....This Too Shall Pass....
