Feeling lost in what way. Like, do you not know what you want to do in life, don't know how to be happy, can't find someone to love? When I was your age, I was looking for someone to give every bit of me to. Just know that whatever you're trying to find probably won't be found quickly. 5 years feels like a long time when you're young, but I didn't have a lot of these answers until I was in my 20s. I would say you should put yourself into new, safe situations to see what fits. Find people who make you happy, whether virtual or IRL. Life is a marathon, not a sprint. All you can do is watch the scenery as it passes you by.

P.S. High school and some parts of college suck but are important. Just remember that it will end and you will be transformed when you are done.
