Loneliness not lonliness .. otherwise your title is okay, probably a bit too lengthy.

'Adrift in a sea,
of loneliness
and lost dreams.

Feeling jealous,
and scorning
those who love.'

`I think that your first stanza would read better in your perspective- something like this:

'Adrift in a sea
of loneliness
and lost dreams...

I feel jealous;
scorning
those who love.'

That might work if you were to change the entire poem as 1st person.

'[Hurt].. by the anger that bleed's in your soul.'
`The brackets around hurt are okay, but you dont need the two dots after it and bleeds doesnt need a apostrophe

'Grasp life's horn's with a pull and a tug'
`A pull and a tug are nearly the same thing. So I dont think they are both needed here.

'Salvage your heart,
because there are those
who just need a friend.'
`I love what you said here, but your poem was a bit awkward in that none of it really rhymed but a few select lines. So the flow was a bit odd for me

Interesting poem, a good job but needs some editing.
