First time getting into an accident and hit someone else, now I don't feel like driving.

For context, I have only driven for two months but I have my license and had training. I drive my family's old motorcycle for commute which really needs more maintenance which I'm saving up for. I was driving to a gas station from work to get more air for my front tire when suddenly something hit my face near my eye and I had to swat away quickly (Wore an open faced helmet). When I got my eyes back into the road, a motorcycle suddenly slowed down in front of me and I ended up rear ending him. I wasn't driving fast, maybe around 15-20 mph. I managed to brake in time but my front wheel brake couldn't stop the momentum. Thankfully he was fine, just sprained his foot. But he had heart problems and I got really worried. I did take responsibility and he was kind enough to be understanding and just asked to pay for damages on his motorcycle.

But now I don't feel safe driving anymore. I know accidents happen and it could've gone worse but my dad yelled at my ear telling me how reckless I am. I feel like the accident was out of my control but my dad drives the same motorcycle a few times and wears open faced helmets too and has never gotten into an accident. I don't know what to think except that I don't feel confident behing behind the wheel, or handlebars more accurately.
