stop feeling guilty about setting personal boundaries

I need a boss who understands when I need to take the day off because I can't stop crying. I need a job that lets me set my own boundaries, because I am different. Unfortunately not many business owners are the type of people who would understand that being a Highly Sensitive Person means if I am not on my game, my work will seriously suffer. I do not respond to pressure and criticism but to positive guidance and encouragement. Sometimes life is overwhelming and unfortunately I can't just "leave my personal life at the door" when coming to work. Everything takes longer for me to process and fully understand, I need time to come to peace when something shakes me.

This is discouraged in the work place. I think it is very unfair. I know that some jobs give you personal days, but I have never worked somewhere where I was able to do that. I have never had this opportunity, and actually this is something I really need in my life as an HSP. The ability to say no to life when it gets overwhelming and take time to rejuvenate so I can continue on in peace and with motivation instead of drudging along with resistance. Life is hard and I think everyone should have the ability to take a day off when they are feeling a mental drainage/explosion. Why is it less manageable to get that across in the workplace than having a physical ailment?

I shouldn't have to feel guilty when something is preventing me from working, whether it be mental, physical, personal or not. Normally in Germany, where I live, it is no problem to take a day when you need it, but I don't work at a company that runs with the regular ways so I am out of luck. It is definitely time for a change in my work, which of course brings on more anxiety. I enjoy a lot of things about being an HSP, but sometimes I wish I could just let things go and move on easily, I wish it didn't feel so heavy to jump into something new, especially when it comes to my work. I want to feel purpose in what I am doing, even with the anxiety produced by looking for a new job in a foreign country. I deserve more and I need to learn to not be afraid to go for what I want and need in life. Of course when I say I deserve more, I also mean everyone. Everyone deserves to go for their own version of gold!
