Aslamualikum how are you ?
Hope you all are fine and enjoy your days..
every person have these life cycle of mood ..
1.disbelief
2.Anger
3.Sadness
4.Acceptance
5.optimism
when its matter not in favouable then he/she totally disagree and there belief on things up or down their mood in fall because according to their though their plans are not work....
then they become anger and if they have any post or job then they release their angerness on other junior employee etc
but if they have no authorities then thay because sad ...
sadness is so lonely feeling (i want and suggest if you come out from this phase please setup your mind and brain washing is necessary )
After a time Or on time If they accept their current matter and result mean accept the matter and belief on Allah so this situation lead to OPtimism ...
please make sure your mind understand you decision and first of all agree your mind!!!
Different situations set our mood and it happen for this life cycle. You have explain it very nicely.
