From the Catechism:
II. THE FALL OF THE ANGELS
391 Behind the disobedient choice of our first parents lurks a seductive voice, opposed to God, which makes them fall into death out of envy.266 Scripture and the Church’s Tradition see in this being a fallen angel, called “Satan” or the “devil”.267 The Church teaches that Satan was at first a good angel, made by God: "The devil and the other demons were indeed created naturally good by God, but they became evil by their own doing."268
392 Scripture speaks of a sin of these angels.269 This “fall” consists in the free choice of these created spirits, who radically and irrevocably rejected God and his reign. We find a reflection of that rebellion in the tempter’s words to our first parents: "You will be like God."270 The devil “has sinned from the beginning”; he is “a liar and the father of lies”.271
393 It is the irrevocable character of their choice, and not a defect in the infinite divine mercy, that makes the angels’ sin unforgivable. "There is no repentance for the angels after their fall, just as there is no repentance for men after death."272
394 Scripture witnesses to the disastrous influence of the one Jesus calls “a murderer from the beginning”, who would even try to divert Jesus from the mission received from his Father.273 "The reason the Son of God appeared was to destroy the works of the devil."274 In its consequences the gravest of these works was the mendacious seduction that led man to disobey God.
395 The power of Satan is, nonetheless, not infinite. He is only a creature, powerful from the fact that he is pure spirit, but still a creature. He cannot prevent the building up of God’s reign. Although Satan may act in the world out of hatred for God and his kingdom in Christ Jesus, and although his action may cause grave injuries - of a spiritual nature and, indirectly, even of a physical nature- to each man and to society, the action is permitted by divine providence which with strength and gentleness guides human and cosmic history. It is a great mystery that providence should permit diabolical activity, but "we know that in everything God works for good with those who love him."275
Here it specifically teaches that demons are fallen angels. The Catechism teaches that they are created beings of pure spirit capable of acting in the world.

I don’t think Palm Tree is trying to insult you. He just doesn’t believe in the evil supernatural and views it as superstition. I think he is trying in his own way, to help you; to keep you from being scared. He certainly has gotten your dander up and is making you angry instead of afraid so that is a help. Direct that anger towards your fear and refuse to let it have any power over you. Christ has won the victory. You are washed in His Precious Blood.
He does have a point about all of us jumping in immediately and saying, without any investigation, that this is definitely demonic activity. That is why my first recommendation was to see a priest about it. I think it is highly likely from what you describe so I gave you the tools, things you can do, that I use to combat it, having experienced it myself. It is not superstition but faith in God, in Christ’s victory over sin and death.
Furthermore, nothing of what we have recommended is against any Church practice or teaching. Indeed, most of it is what we should be doing all the time anyway. If there were anything wrong with the pious use of sacramentals, the Church would have fobidden them long ago and we would have no holy water fonts at the entrance to the church. One of the first sacramentals, I think, were the pieces of cloth that had been touched by Paul that were used to heal people so the use goes right back to the scriptures.
I don’t know if you play any sacred music, or sing at all, but it might be time to start. There is a lot of good classical sacred music out there. I would recommend that you start and end your practice with a hymn to God. Offer your practice to Him in praise. (just say something like, Father, I offer You my practice today. May I play well for the praise and glory of Your Name. I ask this in the Name of Jesus, Amen)
So glad to hear that you are getting some relief. I’m continuing to pray for you.
