Which western country you based at? I think it's a very bad idea. If you have no money there you will be ill treated and oppressed by almost everyone. I don't recommend sleeping outdoors under any tree as it is highly unsafe for women and many unsavory characters that are drunk or high on drugs prowl the countryside looking for easy targets. At your age there's the serious risk of developing diseases etc.
As an alternative you could immerse yourself in Gurbani,Keertan,Katha,Simran in the comfort and safety of your home or the nearest Gurdwara.
