I've been there. I'm Catholic so the only advice I can give is based on my faith. The 1st thing I did was prayer warrior. I had a prayer schedule to include mass, rosary, chaplet, scriptures every day. Of course not everyone can do this but do what you can. Schedule it. My intention/attitude was to fight against evil. Every night before bed I prayed the Poor Souls prayer (and 1000 Poor Souls pray for you).

Then thru church I joined a charity. Visiting nursing homes until my health stopped me; now I knit shawls/hat sets/lapghans for the poor and make kits for the homeless.

Adoration: Important. You need time in silence. Sometimes you hear your answer. Once I heard: You already know what to do. You have the commandments, the sacraments, the beatitudes, the rosary. Another time I heard: Your time on earth will be done when your work on earth is done.

With all that goes on these days, I found my attitude changed from despair to a purpose. Hope this helps.
