Have no doubt that G-d will help

The Rebbe Rayatz, in a letter

According to the teaching of our mentor, the Baal Shem Tov, when a person places his trust in G-d but is agonized and worried and sighing, he has not yet attained a complete trust in G-d. For when one's trust in G-d is complete, his unfavorable - or even (G-d forbid) bad - situation should not affect his heart by causing it distress or, certainly, melancholy. Rather, he should do, according to the Torah and mortal understanding, whatever he is able to do, and place his trust in G-d. He should not have even a shadow of a doubt that G-d will help him, inasmuch as His Providence watches over every single created being [...]. All their affairs and even all of their most trivial motions are under the eye of His specific supervision, and it is this Divine Providence that gives life and strength to every living being in the heavens and on earth.
