an oath or a pledge

If I lost this, then I'd be lost,
and I'll agree with anything - as long as Im behind,
I will always settle for less than what I need,
as far as opinionated; who am I to be...
just that

If you follow me, I will follow you
I'll leave almost anything- just to carry on
Giving up my sight so you could see what I mean
Is a worthy cause this time- cause I am finally clean... at last

If you are just fine, then I am desperate
If all your needs are met then there is no more use for me
I'll be lost in the moment and in that there is no good
I'll be there forever, in fact I think I should.... for now
