I need some advice

Hi I apologize for my English first cuz I’m most likely going to do a lot of mistakes writing this

I’m 17 turning 18 in a few weeks and growing up I thought I’d be someone by the age of 18 and now that I am almost 18 i realize I have nothing and I am nothing but that’s not my main problem My main problem is that I just don’t know what to do and what I want

I don’t seek a extremely rich or wealthy life style I would be more than happy with a job that I like to do that gives me decent money to survive. But I just don’t know what I wanna be and if I’m going to regret it or not and if I do, will I ever get out of that job I don’t wanna dedicate my time and possibly trap myself for a job that I might not even like. What if I like the job but I don’t make any money? What if I end up homeless? And on top of everything I sadly am a coward and I do a lot like a lot of mistakes

I’m sorry if I write like a total mess and I know I use a lot of „and“ but I needed to get a little of it off my chest and seek some advice
