Cute, you actually think everyone needs a thesaurus as opposed to simply spending a large amount of time reading and having a broad lexicon.
Words exist to be used for the proper context. Literally none of the words I used are uncommon words when reading articles or books. If you took time, you'd probably notice I tend to use many of them quite commonly. Don't brag about being ignorant; it's silly. If something like that actually triggers you, it says vastly more about your own insecurities and need to vent your crippling depression on others.
