welcome. just a few notices about some grammatical errors (in my mind, which, as most people know, doesn't exsist.)
"Friends should be." perhaps change it to 'Friends we should be.' or remove the period at the end of this statement and find some way to make the next line have a subject and fit with this line.
"I live for today for tomorrow, who knows." my thought that it should be 'I live for today; but tomorrow, who knows?' or if not but, then some other appropriate word.
otherwise, it is a wonderful poem and I'm quite surprised that it hasn't been commented on yet. hope to see you around.
