It's "Here I Go Again" by Whitesnake :)

Here I Go Again
Whitesnake  (I believe it was released in 1987)

I don't know where I'm goin
but I sure know where I've been
hanging on the promises in songs of yesterday.
An' I've made up my mind, I ain't wasting no more time
but here I go again, here I go again.

Tho' I keep searching for an answer
I never seem to find what I'm looking for.
Oh Lord, I pray you give me strength to carry on
'cos I know what it means to walk along the lonely street of dreams.

Here I go again on my own
goin' down the only road I've ever known.
Like a drifter I was born to walk alone.
An' I've made up my mind, I ain't wasting no more time.

Just another heart in need of rescue
waiting on love's sweet charity
an' I'm gonna hold on for the rest of my days
'cos I know what it means to walk along the lonely street of dreams.

Here I go again on my own
goin' down the only road I've ever known.
Like a hobo I was born to walk alone.
An' I've made up my mind, I ain't wasting no more time
but here I go again, here I go again,
here I go again, here I go.

An' I've made up my mind, I ain't wasting no more time.

Here I go again on my own
goin' down the only road I've ever known.
Like a drifter I was born to walk alone
'cos I know what it means to walk along the lonely street of dreams.

Here I go again on my own
goin' down the only road I've ever known.
Like a drifter I was born to walk alone.
An' I've made up my mind, I ain't wasting no more time
but here I go again, here I go again,
here I go again, here I go,
here I go again.
