Got diagnosed with several anxiety disorders and I disagree mate. Went through all the treatment, CBT etc none of which were any use whatsoever. Tried medication and didn't feel it was worth a wank....
It's an environmental thing to me, Imo it's the same with a lot of mental health. You as an individual have to take responsible for how you feel and make the effort to change your behaviour, change your environment and thus gain control of the problem..... Grown men shouldn't be copping out and saying " oh I have to feel this way as my brain tells me ".... They need to be proactive in making and finding their solutions and alleviating the stress.
Not the liberal opinion, people will contest this but I've got an array of mental health issues I've successfully battled in various ways and I'm the happiest I've been, we'll ever.... So the proof is in the pudding. Don't talk about it much as why would I but I've experienced it and I know how I came out on top....
Do something about it, remove the root issue of your anxieties and master your own emotions is my advice....
