You would be surprised how many close friends I know that suffer with stress and anxiety. It's very common and nothing to be ashamed of. It just needs to be managed, we live in a time where everything is fast, rushed, intense and there never seems to be chance to relax and give yourself time out whilst thinking about work, relationships, money, we just need to remember to slow down, look after ourselves and realise nothing has to be rushed. Take a step back and look at a particular situation and deal with it in your own time. Just remember, it happens to more people than you can ever imagine, some may just not show it, so you're not alone.
Here's a great article from MindBodyGreen on how Reiki can help deal with stress & anxiety.
Look after yourself. x
