Its times like that when you need to start looking into the past... thinking about how far you have already come. Whether you have just started recovery, or you have been in recovery for 2 years..... you have overcome some form of obstacle. Or maybe its just in general life.... for me personally, i sometimes have to look back in the past remind myself that this little stressful situation, ive been in a similar one a few months ago and i made it through. Remind myself of all those times i thought i couldnt get all my work done, or the times the anxiety was too much i didnt see how i could keep living or when i felt like just giving up because life seemed too tough. But i pushed through.... and sometimes all you need is that little motivation from your own past.... to see that you are stronger than you think and come overcome more than you believe.
I often dont recommend thinking too much about the past, unless you are learning from your mistakes, because nostalgia can often make the past seem like a better place when you are struggling in the present.
