yes. you can grow in some ways, make small changes, but your anxiety will probably never be completely eradicated. some people in this world are more anxious than others, it is just a fact of life. there is a point where you just have to accept it as part of who you are.
i say this because initially most people view anxiety as something to be cured. in my experience and observations, this is just not so. you can throw a pill at it, but what happens? it comes back when the pill is gone. same with alcohol. you can become an alcoholic or pill popper, but when you stop taking these the anxiety is still going to be there. so, you just need to adapt in ways that are best for you and live with it.
i recommend CBT (cognitive behavioral therapy). if you can get counseling, talk to your counselor about that. if not, go to the library and check out books on the subject.
good luck!
