To be honest I am going through a huge baggage of health issues and I need to give vent to my frustration, but I hate focusing on negative thoughts, but I do allow myself to do this once in a while to let off steam.
I hope a miracle is happening to you and that feeling down or frustrated is okay. We are humans, and we are not perfect.
As soon as we attained that state of highest realization, everyone would be able to enjoy heaven on earth.
Get angry, let it out. It's ok.
We are allowed to vent. It shall pass.
