Its ok to have a bad day.
I dont know who told you that you can’t have a bad day. I don’t know who told any of us that we can’t have a bad day, but I know we all feel as though we can’t.
Its so important for everyone to realize that life is FULL of emotions. Good and bad. Of course we all dream of having a life with little to no problems But honestly, how realistic is that? Lol what matters is how you come out of it. Not everyday is going to be sunshine and sprinkles, but that cloud you feel like you are under will always pass.
It it would be completely unfeasible to think everyday will continue with no problem. So why punish yourself for your natural feelings.
Those feelings will pass though. That frustration will pass. That solution, you will find it. Your bad day will pass. We get to start over tomorrow!
