You sure you're T and not F?
I used alcohol for all kinds of reasons, but never to forget.
I've been sober for years now, I quit using any mentally altering substances when I was 21. Before that, I've used in order to feel miserable and bad about myself. In order to feel alive and angry. In order to feel human. A very misformed human. But I never wanted to forget, anything. Not a single thing ever.
I did not drink to escape. I drank to experience. Because my sober self was all in control. Had it all figured out. But I didn't want things to be that easy. I wanted to feel pain about what I had experienced. I didUn't want to feel ok with it.
And I was young. When you're young, you're influenced by those around you. Rolemodels and whatnot. And they way I dealt with things, wasn't how others dealt with things. Made me feel alien, different. Alcohol made me act more like those around me. Anger, pain, emotional. All which seems so important to other people. Like it's important in judging how good you are as a human being. Without feeling pain, how can you tell right from wrong? It's logical that right can't be measured, if you don't know what wrong really is, and it seemed that wrong wasn't to me what it was to others. And I wanted to feel more like they do.. So, I didn't want to feel right, because feeling right would be wrong in the eyes around me. So I did whatever I could to feel wrong about it. Alcohol made me do that.
Anyhow, I grew up, snapped out of it. I became self aware, egotistical and confident. And drinking wasn't an option anymore. Just like that I gave up on it, and felt better ever since.
Anyways, I don't think an INTP can really escape anything. And I doubt there are INTP's that don't realize that. There may be a thousand different reasons for INTP's to use substances. But trying to escape ain't one of them.
