Back Handspring Layout step-out on beam

[Gymnastleia]

Hi! My name is Leia, I am a level 9 gymnast and I have been having trouble on my beam series and I don't know what to do? I feel like I start over everyday when I get to beam and I don't feel confident... I competed a back handspring back handspring last year and my series is new this year (bhs loso). I get so nervous when we go to beam and when I am standing up on the beam before my series I am so nervous. I think I am just nervous about falling because it has happened to me a lot lately My coach doesn't let us compete with a mat and I need some help on what do or think of that could help me relax and get through this mental block!!
