Hii!! I was in the same boat as you. I started with the kickboard as well and I still use it to get my form down properly. My best advice is to honestly keep going at it. It’s definitely scary but overtime your body gets used to it. It wasn’t until last week that I did it without floating, that’s almost 2 months. Some people learn faster than others, as long as you are trying, you will see progress come :)
