First of all, regain your faith. The God of the KJV Bible is the God of the Universe, and he is expressed in Father, Son, and Spirit. Every single thing on the planet aligns with this when you parse down to primary sources. Everything.

Experientially, also. Sin leads to destruction one way or another. Righteousness leads to construction one way or another.

Second of all, even if you have to pretend to have faith, if you ACT AS IF and live your life righteously (according to New Testatment as given by God, not as re-interpreted by men) ---
your life WILL improve.

Be HONEST.
Be LOYAL.
Be HARDWORKING.
Be HELPFUL.
Be KIND.
Be GENEROUS.

Most importantly BE HUMBLE. You have made yourself god by shunning your faith. Do YOU know everything and have all the answers? Are YOU more worthy of a good life than others? Can YOU make miracles happen through circumstances that line up to your benefit?

NO to all of that.

Ask God for what you want (that's righteous) and then be obedient and determine to be so for the rest of your life. I GUARANTEE you in ONE year you will be better off than you are now.

GUARANTEE.
