I got chills as I read your post because I see you as an incredibly powerful person. The way you have managed to reform your self through your challenges and successes is powerful. Leaving that job was an incredibly powerful and courageous move. As they say, courage is found as we move through fear. Without fear, courage cannot be experienced. I hope you don't continue to feel bad about not giving 2 weeks notice
when it comes to leaving your job. In my opinion, you managed well. You managed to convey the challenges you faced, yet they
chose to manage through ignoring the need to support you. You left
suddenly because of a fault in their management - neglect. In a way, you did give fair warning, they did not listen.
One of the mantras I live by is 'Every challenge holds the potential to either depress me or raise me (to a greater version of myself)'. The enormous challenges are potentially depressing because it's the nature of enormous ones to be deeply reforming. The enormous challenges are fearful and they can be filled with a kind of grief that sees us letting go of parts of our self, our identity. 'Who am I if I am not fearful? Who am I if I am not easygoing, like everyone wants me to be? Who am I if cannot tolerate the intolerable?' While some may say 'I am nothing without my fear, I am difficult if not easygoing and weak if I cannot tolerate things', others may say 'I am fearless. I am challenging when it comes to that which must be challenged or questioned. I am strong because of what I will not tolerate'. I believe we gradually find love for our self through the challenges we rise to. We raise our self, to love our self. We graduate. Each challenge we face where we reach the conclusion 'I deserve better', can have us looking back not just on the challenges themselves but also on the graduation we've achieved. Such graduation will not always be obvious by the way.
Personally, I have no idea where I will end up in life. It doesn't bother me not knowing. What I have come to care about, since having left my depression behind me some time ago, is the fact that I am graduating through my life. This will always be my #1 goal - reforming myself.
I believe it is the nature of life, to present challenges. As long as we're alive, we will face them. It is the challenges themselves that reform us, to come to know the best in our self. To live fearlessly, with faith in our self, is perhaps one of the greatest challenges of all.
