Taghavi! I read your poem, and I quite like it. It is your poem, so you have a right to put in it any words you like. However, just to get the English right, you might like to change the last two lines to: 'I would go there/If I knew where 'there' was'
Good luck with your poetry. (See if you can find a book of Robert Frost's poems. I particularly like his poems. They are more like stories.)
