I need some help here!?

I have had some problems with my family for about a year now and Im just now starting to get back their trust. I dont have a job but I have a case still "under review" and I also joined the Military. I want to better improve my life and my family knows that but they keep insisting on making my life harder. My dad is well off with his career and has money and my stepmom is a stay at home mom. My lil sister is about to go off to college. I have been out of school for 2 years now. I went to college but I didnt make the grades. My dad told me to take the next year off to think about what I wanna do with my life and what I wanna major in. Well during that time things between me n my family became strained and now Im building it bak up. What Im tryin to say here is whatever I try to do it always seems like people keep putting me down and everytime I try to advance to better my life somebody always is in the way to stop it from happening. I want to make somethin of myself and be somebody. Thats why I joined the military. I was unknowingly involved in something that got me in trouble and that is what changed me but Im still not done with it. It seems like EVERYthing I do there is Always a Roadblock that gets in my way. I just want everything to go bak to the way it used to be but I dont know how to.
