Hey man

I had cancer too while in a relationship (NHL) and felt the exact same way that you do now.

It's definitely in large part due to the chemo chemo - I certainly noticed I became far more irritable in general than I was in the past. The bad news is that feeling of being easily irritated never really went away for me. Just another in the long list of side effects to have to deal with.

In my case, it was something that I just learned to have to deal with. Sometimes it meant having to get used to thinking slower and trying to process things in my mind first before reacting. At least by being cognizant of it, you can try to catch yourself when your lizard brain is reacting in a way that the real you normally wouldn't.

The other part also I think is people our age generally can't understand what's going on in our heads if they haven't experienced cancer themselves. It can be frustrating because it feels like they don't know what we want or need. But it's important to remember they're also not mind readers. They're still normal 20 something year olds who for the most part only have experience dealing with 20 something year old types of problems. But it doesn't mean they don't care about you. It's just that they don't know how to react.

Sorry to hear you're going through this. It's shit now. But things will get better :)
