Please pray for me, I’m struggling with doubt

Been posting about this daily until I get to the other side of this thing. I’m going through a period of doubt right now, and it’s been really difficult. I’m worried I’m going to commit apostasy as what may be indicated in Hebrews 6. I’m already worried that I’ve already done it as I have a couple instances in mind that makes me think I might’ve done it. Please pray that God would unharden my heart and that it would remain soft. That I would not fall into sin and that I would repent of any sin in my life and be fully reconciled with Him. That He would confirm His presence to me in such a way that my doubts and fears would dissipate. Not necessarily like sign and wonders but just something I would believe and trust in. If you could also pray that God would deliver me from all my OCD and intrusive thoughts that would also be helpful. I also struggle with lust, that’s the sin I’m mainly worried that is going to harden my heart, so if you could pray for that too - that would be great. I feel like there has been a lot of demonic influence going around in my life which has brought this on, so please pray over that. Finally please pray that God would increase my belief, faith, and trust as well as that I would not fall away either in doubt or just in general. Thanks for any prayers you may give, I really need it
