In my book, faliure is only when we fail to realize that we have slipped and fail to muster the courage to start again. If one slips off the mountain, shrugs and walks away, he will never reach the summit. If one slips off the mountain, and resolves to climb again (yes, with better gear and safety nets) then he hasn't failed. He merely has taken a small detour, but the summit is still his for the taking!!!
There is nothing "Poshut" about you, You are a YID!!! and Hashem loves you! Start that climb again my dear brother. We are here to help, and Hashem will catch you if you fall!
