What do the scriptures say on how to calm oneself down when one is faced with exiting his comfort zone? As long as I can remember, I've always became quite nervous with uncomfortable feelings whenever it was time to leave my comfort zone behind and jump into the cold. Unfortunately it affects my thinking process, my appetite, and my behaviours in general. I hate being a nervous wreck and I'd rather be calm when the storm hits.
What advice can Jewish sources give me on that particular issue?
I can say from experience to say Tehillim 23 and meditate on the meaning of the words which is in essence a personal experience of Dovid Hamelech when he was on the run outside his "comfort zone" how thinking About Hashem how really every human is helpless without His constant presence and guidance. Throughout the generations we have survived through his embrace G-d is constantly with us and everything He orchestrates will be Good for us.
ה' רֹעִי לֹא אֶחְסָר בִּנְאוֹת דֶּשֶׁא יַרְבִּיצֵנִי עַל מֵי מְנֻחוֹת יְנַהֲלֵנִי נַפְשִׁי יְשׁוֹבֵב יַנְחֵנִי בְמַעְגְּלֵי צֶדֶק לְמַעַן שְׁמוֹ גַּם כִּי אֵלֵךְ בְּגֵיא צַלְמָוֶת לֹא אִירָא רָע כִּי אַתָּה עִמָּדִי שִׁבְטְךָ וּמִשְׁעַנְתֶּךָ הֵמָּה יְנַחֲמֻנִי
The LORD is my shepherd; I lack nothing.He makes me lie down in green pastures; He leads me to water in places of peace; He reinvigorates my life; He guides me in right paths as befits His name.Though I walk through a valley of deepest darkness, I fear no harm, for You are with me; Your rod and Your staff—they comfort me.
