Bardichev,
I would like to offer you a very well thought out aitza.
Try to LIGHTEN UP.
Two people can "outwardly" be doing the very same thing, (like shmiras a bris for example), and yet on the "inside", they are completely different.
1) you can be doing shmiras a bris by: Running franticly from the y"h thereby feeling pressure, fear,anxiety, eventual exhuastion, which in the end can lead to a fall. Why? It is the VERY stress, and anxiety of this type of approach which beackons us to return to the acting out, in order to sooth our pains so to speak.
2) you can be doing shmiras a bris by: Instead of running FROM the y"h, RUNNING towards Hashem. Your entire focus contrary to the above, is one of GOING somewhere that I wish to be (hashem), rather than running from a place I am frightened of. The first option produces anxiety which can feed the problem, the second, i.e running TO Hashem's palace will produce a different type of feeling.....because you are doing something completely different. You are building and strengthening yourself with each step, as opposed to the "fleeing", which causes tiredness with each step.
