Pencil Drawing - I Don't Know What to Feel

I've never been a person connected to their feelings.
Negative feelings overwhelm me all the time though, depression, anxiety, fear these things take a hold of me, and they don't let go.
I have never been able to express these things properly neither through words nor art.
I try and try but feel like my work is meaningless.
It scares me that I'm not good enough.
