When do we experience grief
The five stages of grief are:
We can go through a period of grief resolution after losing a person, losing an opportunity, losing something that we worked hard for, losing a relationship, after surviving a tragedy, after hurting others and reflecting on the heavy weight that we have placed upon our consciousness.
All feelings are valid and nobody can tell you how long you can feel what you feel for.
Only you can decide what to do, only you can control how you express your emotions and how to process your stimuli.
Think of constructive, creative ways to process and you could be a light to this world even at your worst.
Write something about yourself. No need to be fancy, just an overview.
