The things that make me, Me: Anxiety

I feel, or believe that, I'm the most negative person I know in my life. That's not right, is it? I don't think so.
I suffer from severe anxiety, though, not taking medication for it (any longer). I was from end of March until the start of May (2014), but I felt like it was doing more harm than good (headaches, major fatigue, irritability and even less motivation than prior to medication) and the $40 a month my mum was spending on it (yes, I'm currently unemployed) just felt like it wasn't worth it. So, I weaned myself off the medication.
This anxiety affects literally everything I do; how I socialise/talk to people, determining whether I go out or stay at home, what I do for the day, how much makeup I wear, what I wear, how I treat others.. I hate it, and it's not an easy thing to overcome. I was officially diagnosed last year, but thinking back, I've been dealing with it since primary school.

I want to overcome this, or at least weaken its intensity and control it has over me. I need change, as much as I fear it. I need more confidence, as hard work it seems.. But hard work pays off, right?
