Driving in the rain, almost got into an accident how can I make sure it doesn’t happen again?

This was my first time driving in heavy rain. I was being too reckless but a car came at an abrupt stop and I tried to break but I lost control and had to swerve to the right quickly because my car did not stop in time. It was scary so I made to drive slowly around 25mph the rest of the way but I wasn’t going incredibly fast, I was going about 35 mph. I usually do 40 to 45. But I just need to make sure it doesn’t happen again. I’ve had my license since janurary and I don’t want an accident already.
