I am here. and if I am here, I am here for a reason.

The logic doesn't hold. Being somewhere doesn't imply a purpose behind it. Most of your circumstances came from other people's decisions and a considerable amount of chance.

Which turns out to be freeing rather than bleak. If the reason wasn't handed to you, it isn't fixed either, and you cannot fail at finding something that was never hidden. Reasons get made. Someone becomes a nurse and, twenty years on, the reason looks obvious — it was under construction the entire time.

You are here. That's the fact. The reason is your assignment, not your inheritance.
