I suck at chess and hate losing. How I deal with unadulterated rage?

If you are a kid, then you attitude towards chess is wrong but it'll sort itself out so probably nothing to worry about. Now, if you are older/adult, then the same still apply WRT attitude, except you really have a big problem and probably can benefit from professional psychiatric help.
Yes, my advice doesn't directly address "how to improve in chess", but it can help you a lot long term in everything (including chess).

Here's hoping your blood boils...
