That blank canvas is just mocking me

I've had writers block for I don't know how long now, it's making me severely question whether or not I have any musical talents. I feel like I could write anything else but lyrics write now, but the itch is still there to create something. I get a couple lines of something I really like, but then that's it, ideas flash and all I get is brief glimpse of them and then they're gone again, and all I'm left with is a picture of something scurrying across the lens. I want to do music so badly, I feel I have potential to excel in some sort of creative medium, but I don't know how to unlock it. The desire is there, I just don't know how to access it, which makes it even more frustrating, I'm too left brained. My brain's retarded. I used to be fairly prolific when it came to song writing, there was a span of a couple months where I was just churning them out, I wonder if it has to do with the fact I've just had so much free time not having a job, that I've got nothing to be inspired from. Every day's the same pretty much and I don't know what to do to fill that gap. I mean I've still got a pretty decent amount of music, but no lyrics.

Who taught you to keep your eyes to the ground
When you're getting talked down to?
Don't you miss having thoughts of your own?
Don't you miss being happy all alone?
-
You said "Just take my hand, we could travel the world,
Leave it all behind and see what's in store."
But you know, it's not me, you're thinking of
And soon you'll see
You say what you want me to say
But those words aren't mine
-
You wanna know where our love has gone
I can't promise you I'll speak the truth
These spaces get so tight
That I feel I can't go on
Ain't nothin you gonna say, girl, to make me right.
-
You call me up on the telephone
To let me know how you're doing on your own
I thought you could tell by the straining in my voice
That it was a call I would've never cared to have known.
You say you're tired of your words on deaf ears
Tell me why you feel the need to keep me here.
You say you're tired of these unrequited loves
So now you're looking for your answers from above

Oh you got me tired
Got me tired of wasting my time

Now I'm telling my secrets to county store patrons
Looking for some sort of outside perspective or explanation
But all I receive from them are broken stares
Got to keep moving, rushing, pushing,
Can't spare the time

Oh you know I'm tired
Tired of wasting my time.

I left my baby in the doorway
Waving good-bye with tears in her eyes

Now don't tell me that you love me,
Don't tell me that you care

'Cause she had them wondering eyes,
And a cold cold heart,
One thing I can tell ya
She sure played the part

Now don't you tell me that you love me
Don't tell me that you care.

See, these are all just so sparse, and none of them are very good, I like the music that goes along with them though, but my brain just stops thinking about what comes afterward.
