What Brings Anxiety?

Hi.I`m 31 yo M and I suffer from anxiety. My doctor told me to relax, walk in nature, stuff like that. I feel like I`m going to die, and all he says is relax! Anyway, I`m kind of a managing to treat my anxiety feeling, but would like to know what could be the cause of my problem. I know some people who suffer from anxiety had a stressful event, an accident or something, but I`m not that case.

Hi. I`m that case, I`ve had a swimming accident last summer, and I have barely managed to stay alive. Now I fear from dying and I`m afraid of water. Anxiety may be caused by a mental or physical condition, or drugs. Stress can cause anxiety too. And I mean any kind of stress, at work, school, home, financial stress … If you didn`t have any kind of an accident, maybe you are under some great stress at work, or at home?
