My go to aspiration when I am having a rough time or need assistance is an ancient one I heard of that people used to try and say a thousand times a day:
"Lord Jesus Christ crucified have mercy on me (us)!"
Also this one helps refocus my mind and remind me of why I am here on earth:
"My God, I believe, I adore, I trust, and I love thee! I beg pardon for those who do not believe, do not adore, do not trust, and do not love Thee." (Fatima prayer)
