"Have no fears, put all your faith in Christ" is great advice--and far easier said than done.
Hold onto your faith as well as you can at this point, He understands your whole situation, and will quickly forgive you for losing some faith. You're doing the right thing by coming on here--it says a lot about your deep desire to stay with God.
As soon as I post this, I'm going to say a Chaplet to St. Michael in your honor--I'm including the link if you want to try it, too. Now is not the time to debate the intercession of saints--you need help as soon and as strong as possible. I've sent this to other people, even non-Catholics, and it's worked remarkably well, a tank in your spiritual warfare. Michael the Archangel was a powerful spiritual warrior & intercessor in Scripture, and he will be for you, too.
St. Michael the Archangel, defend us in battle;
Be our protection against the wickedness & snares of the devil.
May God rebuke him, we humbly pray;
And do thou, O Prince of the Heavenly Host,
Thrust into Hell Satan & all the evil spirits who prowl about the world, seeking the ruin of souls.
When God is for us, who can be against us?
Don't worry, keep on truckin', you'll make it in the end.
