My advice is the same as most others: you need to have clear priorities in your life.
If you are a Spiritual Satanist, spiritual activities are the main pillar of your life. Everything else revolves around them. When you decide what to do in a day, you place spiritual activities first in your schedule. Everything else is built around them.
It doesn't matter what day it is. By skipping, you also damage your self-discipline which is built up by doing things when we don't want to, when we don't feel like it, when we're tired or sick, etc. Undermining self-discipline has harmful consequences on life as a whole, open the door to the ignorance and decay of those without, the NPCs, the entropic forces that work to annihilate us.
Furthermore, meditation is primary need. If you don't feel like eating today, do you stop eating for a whole day? If you don't feel like sleeping today, do you stop sleeping for a whole day? If you don't feel like drinking today, do you stop drinking for a whole day? If you don't feel like going to the toilet, do you let yourself piss and shit your pants?
Your soul requires spiritual light to function properly, which is absorbed through meditation. If you don't give to it, is like telling your body "Sorry, no food or water today!", It also requires to be clean. Skipping cleaning is in fact worse than not showering for a day or not cleaning your teeth for day, especially when you're exposed to the sewer-like energies of most people who let their souls rot. Skipping protection is like inviting the enemy to do more damage.
Every action has consequences.
