I need solutions

Guys, I hope to find a solution to these problems that are hindering my development as a goalkeeper. The first problem is a mental one; I'm afraid of diving and falling to the sides (I don't know the safest way to land). When I try to dive and overcome my fears, I injure myself on the knee or elbow. I also hesitate to come out for crosses and long balls. The second problem is technical; when I catch a shot, I automatically let go and catch it the second time before it touches the ground, whether it's a shot from the center, a corner, or a cross. (Sorry for the language; I wrote it as a translation due to my weak English language skills.)
