#79738 Mental Health

You will need to do a working every single day consistently until the issue is solved.

Ansuz x 40 "I am completely and permanently free of all mental illness in the best way for me" choose a good date and stay consistent.

Yes, it is possible, but it depends a lot on each person. Some take longer and others take less time to get rid of it. In my case, it took me four and a half years to get rid of just ONE. I'm not saying this to frustrate you, but as an example that works but will vary greatly. You just need to focus on your journey to get rid of it.
I wouldn't recommend overloading yourself with it all the time, as sometimes it may not even result in what you want.
Cleansing is necessary here. Many may think that cleansing alone doesn't do much, but it does. Then you have to see what works for you and what doesn't, deprogramming with hypnosis, magical works, certain Gods ( like your Guardian ) can help with that too. There are many options.

Is there a way to permanently rid myself of mental illness through meditations/spells? Must I complete a specific meditation/ritual for each illness every week? That seems tedious and improbable, long-term.

What is the nature of the illness? That can alter how you proceed.

I have done High Priestess Lydia's emotional healing spells on several occasions and I am much more healed now.

Besides what others have said, when it comes to changing the mind, hypnosis is the most superior method.
