Is sitting through church hard for anyone?

I've been doing more research on the ins and outs of Catholicism, and man are the guidelines very strict. They're not bad in any sense, and following them makes for a good person, but with ocd these guidelines seem near impossible to properly follow. For example, it's a mortal sin to have an impure thought, and commiting a mortal sin puts you in a state of sin. This means you cannot receive the eucharist (body of Christ) at mass, which is a way to connect closer to God. You have to confess in order to be free from mortal sin. This is fine and all, but this means in my case I'd have to confess almost every week, which can be so tiring. I'm not trying to bash on my own religion, but these guidelines make it so incredibly difficult for me to feel good about myself. Knowing I'm committing one of the worst forms of sin everyday. Intrusive thoughts are a constant thing, does that make me a child of sin? I even skipped mass today because I feel guilty about being in mortal sin, but skipping mass is also a mortal sin! I feel absolutely terrible about myself right now, and feel as if my connection with God has been cut and it's entirely my fault...

Hi! I have been struggling with ocd for many years of my life, however, I have recently been struggling with religious ocd. Currently my ocd has been putting thought into my mind like, “you shouldn’t go to that party, because “God” doesn’t what you to” or “don’t do this or else it’s going to make “God” mad.” These thoughts have been overall causing me so much anxiety, and truly I don’t know what to do. I’ve been struggling to identify it’s actually Gods voice or not. Also, my ocd has been also making my prayer a very stressful part of my day, which is not how it should feel at all. Now finding peace in prayer feels more like a chore, than a conversation. Does anybody else have ocd like this? If so, any tips?

Today I was listening to a sermon, and it was about pleasing God. Sometimes the preacher mentioned people who are not right with God, and I got scared. Sometimes I wonder what if it is conviction. But then I go and I pray but there’s some anxiety and I feel like I’m trying to force myself to do something. So it feels like either I was triggered by the sermon and as a compulsion I tried to pray really hard, or am I ignoring something? I feel like I am being OCD but I fear what if that is conviction. I know that repentance is not always easy, but I feel like sometimes I put unnecessary burdens on myself.
