Don't give up my friend. This is a phase you are going through. You don't need anyone else - you yourself have to manage this. You shouldn't depend on others. And the fear of having to be on meds all your life is a common thought of those with anxiety/depression/mental illnesses. It is not true. It is entirely dependant on you. I have the same fear but I am determined that I won't be on meds for all my life. And I will take steps to prevent having to be on meds all my life. Not only that, but people with diabetes have to take certain steps their entire life. People with epilepsy have to take meds all their life. There are many people who cannot survive without meds. Is this a weakness? Of course it is not. So don't think of having an anxiety disorder is any different.
We cannot expect that overcoming excess anxiety is going to be an easy ride - we should expect to hit walls. Everything we do, whether it be learning a new skill, maintaining a relationship, or being creative, we always hit walls. It is something that is inevitable (it is unfortunate but true). It is how we progress from there that matters. Giving up is the worse we can do.
Remember it is just a phase.
