i want you to know that i am so sorry to hear how much that car accident seems to have affected you,
but you're coping with it, you are even if it doesn't feel like you are,
you are so brave, and so strong for even making the moves to go back to work at all, no matter how long it will take you to fully feel like you have recovered,
you just need to stay strong and persistent.
i myself, am 22, and was in the passenger seat of a car accident last year - and can relate to how you feel;
the feeling of being alone. no one knows how you feel, because they haven't experienced what you have,
communication is obviously the best way to gain the understanding of others - but just ensure yourself, that you are not alone - people all around the world are dealing with similar circumstances and even though it may seem like all hope is lost,
it is not, you will be able to move forward as long as you stick true to yourself - and mend.
i know how hard it can be, but just do the best you can, that's all anyone can ever ask of you, that's all YOU can ask of yourself.
