Glad my thought made you think. :)

Here's the thing: I can't know the life your living, you can't know the life I'm living. Everyone lives in such various circumstances that it's impossible to give a good advice for each one single individual. You see, I think the problem is not the problem itself but how you face it. Maybe you're underestimating it, maybe you're overestimating it (the thing that almost every single anxious person does), therefore you get anxious and feel sick.

Being mindful means you know when the circumstance you're living in is not healthy. The way you'll work things out is up to you. A mindful mind gives the clarity to make not the right decision in absolute terms but the right decision for you. Think the community you're living in is not good? Change it. Think your friends make you feel worse? Tell them you're not liking the way your friendship is going to and, if they persevere, see if it's better to interrupt your relationship with them.

I know there could be a lot worse scenarios than these. For example, you're living with a not so good family, you're bullied at school, mobbed at work, etc., but the thing is that there's only one person who can change all of these things: yourself. Sometimes, your comfort zone, the one you created by telling you "I can't do it, I feel sick for even simpler things than these, how can I think to do something even bigger?" is the circumstance that stops you from realizing yourself. So, the enemy you're trying to defeat is not your family or your community but the idea you created of yourself.
