My insanity is leaking

Unwanted intrusive thoughts that have a character and persistence of occurrence that make them a real problem, are normal enough for there to have been written books on how to deal with them. It is also normal enough to be referred to as purely obsessional OCD (or POCD).

I have, myself, had a big problems with unwanted thoughts.

I am a bit surprised by the nature of your unwanted thoughts, though, if I have understood things correctly, i.e., that your intrusive thoughts are, e.g., "shut up, I hate you".

In the context of intrusive thoughts, the typical topics described are sexual, religious, and violent, and the transgressing nature of the thoughts are a big part of what fuels them and what makes them distressing.

It is good that you do not see them as your own thoughts, and ignoring them without becoming anxious about it, is a good idea.

While medication may work for you, there are also other ways of trying to lessen/fix OCD problems. E.g., there is cognitive behavioural therapy, which I don't that much about.

Changes in lifestyle, such as changing your way of eating by eliminating certain foods, can, I believe, have an impact mentally, as well as physically.

I suspect that the lessening of my OCD problems also has to do with having mercury fillings from my teeth removed a year ago.
Note, however, that I am just saying that it might have helped me. It has not been a controlled experiment, and I don't know if it will have any impact on others. It can be expensive to get done, so I'm just mentioning it, not saying it will help.

Medicines are tools.

(Sometimes tools of the pharmaceutical corporations to make obscene profits)

These types of situations are sticky, because a simple anxiety issue, or neurological disorder, can be exasperated with medication.

I've had to control panic attacks, once in my life, and didn't realize, for quite some time, that my medication was the root cause of problems. Some meds will definitely help, but not all meds react the same way, with everyone. I developed effects that really interrupted my speech (I found I was zoning out too much) and caused me to feel absent, in daily routine. Even going through severe mental stress, I had to taper off.

With others, it can actually exasperate your hallucinations and even cause them. If you have OCD, or thought that consume you, it can really impede the progress in overcoming compulsions.
My nephew had severe tourettes, with medicine in the mix, it only became worse. Once he got off all meds and started healthy living, working out and dieting, he was able to live, much happier and he fully recovered from his problems. He got into a field of work that made him happy and began a life, he didn't think was possible. Ironically, coincides with him tapering off meds entirely. He was reaching a point of obsession with his thoughts (and they were dark) he tried suicide, he believed he could hurt himself or someone else, due to his aggressive thoughts. I was happy to see him overcome his demons.

Sometimes it takes a new outlook, routine and healthy living. Meds help some, or a lot, I know, but in a lot of cases, with intense medicine regimen, I've seen only hardships.
