I have had a similar situation. In my case, there were a number of painful events in my life and I used them as the "reason" for becoming angry and cynical. I had aversion, but it was ill-will that was my primary. Aversion was a way to prevent hurt or pain, but the ill-will was my protector, in a way. Angry cynic described me best.
In January last year I had an over the top anger episode and decided that was too much. I was drawn to Buddhism, the practice in particular, not the philosophy. I knew my solution was to become calm, not to study someone's words on calm, except the Buddha's words, of course.
In time, I saw that my old enemies were all gone and there was just me to be an enemy to myself - and I was still doing it. A kind soul had pointed me toward the Four Noble Truths and Eightfold Path. Another mentioned the Kalama Sutta, which was central for me. I discovered the quote from the Buddha,"Come and see..." So I did. I began to practice and eventually to meditate.
Some other things began to get my attention. One was the Brahma Viharas, the four immeasurables of loving-kindness, compassion, sympathetic joy, and equanimity. The Buddha was these ways, I wasn't
I thought that was a pretty good lesson for me.
Another thing that got my attention was the concept of emptiness. I could see it at work sometimes in my interactions. I won't try to explain it because that would take a while. But there is one aspect that struck me - the label is not the thing. The things, events, etc., usually have no meaning outside what someone has attached to it. We paste labels on things, then react to the label......the guy who cuts me off in traffic didn't do it to make me mad, he's just late. He isn't a ^%#@#$% like I think he is - another label. I don't really "hate it when that happens." But I can choose to hate, or to just let it be an empty event.
I have nothing to teach, especially in Buddhism, so please take my descriptions as just examples of things that I do. They seem to help me and I hope that they might be of some use to you. Feel free to take them or leave them, they are just my views and limited experience. There's a bunch of others here who can offer advice and suggestions. My caution would be to see what the Buddha says about it, too.
My other caution is to remember that everyone, IMHO, is in a different place on their path, and their opinions reflect that. Opinions are like noses, everybody's got one. Some are more attuned to where they are than others. Some are more able to speak to where you are than others. I sometimes think the Buddha foresaw the internet when he taught the Kalama Sutta
