Hi MicholasMolotov,
This is one of those things, that when it comes up I often read about a black and white “yes” or “no” when it comes to whether one sinned or not by missing mass, and I believe sometimes it can turn into the way the Pharisees used to be in obeying the letter of the law but having cold hearts.
The question I believe is, do you want to go to Mass? do you hunger/thirst for it? Because If you hunger/thirst for the Mass, even if you do miss it, I believe your not sinning, if you don’t hunger/thirst for the Mass, I believe even if you do go, you will simply be paying lip service, *“These people honor me with their lips, but their heart is far from me.” *(Isaiah 29:13)
Sometimes the response as to why people attend mass I believe is “Because we are obligated to”
When people miss mass for no valid reason (e.g. they didn’t feel like going), the church teaches us that this is a sin. However Christ does not want people to attend mass out of fear, guilt or by feeling forced to go. Christ wants us to attend mass because we want to, because we love him and want to receive that enormous gift where he comes down and feeds us with his body, blood, soul and divinity, because we hunger/thirst for that encounter of real love with him through the Holy Eucharist.
If you do not experience that hunger/thirst for the Mass, I believe the following short booklet may help -

And when it comes to confession I believe the following may help out of St Faustina’s Diary.
Jesus to St. Fasutina -
"…when you go to confession, to this fountain of My mercy, the Blood and Water which came forth from My Heart always flows down upon your soul and ennobles it. Every time you go to confession, immerse yourself entirely in My mercy, with great trust, so that I may pour the bounty of My grace upon your soul. When you approach the confessional, know this, that I myself am waiting there for you. I am only hidden by the priest, but I myself act in your soul. Here the misery of the soul meets the God of mercy. Souls draw graces solely with the vessel of trust. If their trust is great, there is no limit to My generosity. The torrents of grace inundate humble souls." (Diary, 1603).
I hope some of this has helped
God Bless You
Thank you for reading
