Crank that Christian music loud in your house if you can and pray often. Sprinkle some holy water in your room and house. Blessed salt helps too. I have horrible intrusive thoughts and there was a point when I hit my lowest low and I felt as if I was under some sort of spiritual attack. I eventually got out of it, but I have been through different challenges after it. Read the bible. Your confessions are working if you do not hold anything back, and the Holy Eucharist is working if you receive in a state of grace. God hears all your prayers and He knows you are struggling right now. Try something to take your mind off of everything. Go on a walk on a sunny day. Read a book, or watch a good movie. If you feel like satan is attacking you, say “not today satan.” and don’t give it a second thought. Of course, this is just my advice, I’m not sure what you have and haven’t tried yet. If I were you, I would seek professional help, especially if it interferes with your daily life or your job. Praying for the best. God bless.
