Lily,

To be worrying about the future is normal. As someone once said…”if you don’t want to worry, be a plant”.
However, as you’d know, over exuberant worrying can be paralysing….and a decision stopper.
Most “what ifs” never ever happen. However, the trick is to, firstly accept that they may happen…that’s life.
Secondly, we need to consider… what is the very worst thing that might happen, if the what ifs come true. Will you die from them?
Probably not. Your life may be detoured or you may have to change plans…but that can often, in itself, bring other exciting things to your life.
So, my tip is to release yourself to the “what ifs” and trust the Universe. Make a decision and calmly deal with the consequences of that decision…as they present themselves. You’ll find it an exhilarating trip.
