Why are some days grey like today

I woke up this morning wondering is there something missing in my life. I was looking up to the sky waiting for the rain to fall down on me. Why is this so hard to believe that I am not capable to throw away my limiting beliefs on this grey and cloudy day. I want the sun to come out, but I know that isn’t possible today. Some days I want to scream out loud what the heck are doing about your life. Maybe I shouldn’t think this way but I do sometimes have to except that life isn’t all a bed of roses. That there is good days and stinky days sometimes.
