I have had many setbacks, at first I thought setbacks were terrible and I tried my best to avoid setbacks - however what I discovered is trying to avoid setbacks made me worse, they made me extremely cautious and afraid to go over the "Line" in case I got another setback - and this brought a whole load of trouble.
When I saw myself anywhere near the "line" and anxiety was creeping up on me I would panic "Oh no not this again, how will I cope
", so it dawned on me my new anxiety was SETBACKS.
Since then I have found that although shitty, setbacks are actually the thing that teach you all about anxiety. You have to go over the "line" with anxiety to learn where the line is, and when you do go over the line, push the boundaries, etc. you have to experience a setback - but that setback is exactly what will teach you what your tolerance levels are and so you end up learning something for next time.
So setbacks are crappy and uncomfortable, but useful - they are the thing that actually guide you FREE of anxiety because how could you learn where your limits are otherwise?
Now that doesn't mean you will never experience anxiety again, never go over the line again - because I think that is impossible. We will always have anxiety so long as we live in a society that produces it (new jobs, moving house, getting married, children, illness, disaster, etc.) and so we must expect setbacks - but we can learn to cope with that and not worry about that and enjoy life again quite successfully.
Now that can be done, and setbacks do get better and a lot easier to cope with - and I can definitely vouch for that!!
