I feel exactly the same. I change my mind about what I want/who I am so often I cant keep up with myself, let alone the people around me. I had this idea a few years ago that I wanted to be a hairdresser coz my bf was one and EVERYONE loved him. My parents liked him more than me. Everyone was just SO interested in him and I was this loser who clung onto him. So i thought if i had the same job as him and the same goals people would like me too! The next minute i hated his guts and hated all hairdressers!
And to this day my parents still ask when Im gonna do my hairdressing course, despite the fact I have literally changed my mind 1000 times! That's not how it works folks- get with the program!
