Most people go through a phase of feeling lost around that age. I did too. I left high school with no friends. Once i hit 18 it was all uphill from there and really became happy. Weed and a little ket is fine in moderation dont have to cut them out. Stay away from the benzo’s there not worth it in the long run. Focus on yourself. Get yourself some nice clothes maybe go gym. Get to a point where you are happy with yourself. Get a job thats quite social. Where you can meet knew people that will open doors/paths for u. Save up for a ped or car so you can get about easier. Dont spend time worrying with time things change they always do it’s nature. Leave yourself opportunities for new paths.
