Another thing to try after you've done some groundwork with her. Loop the lead around her neck before you unclip it from her halter (or take the halter off). You still have some control that way and can prevent her from running off. Keep her attn on you and only when she is calm slowly let her go. Don't jump back either just step slowly away. You can't feed into her high energy in this. Ideally your horse should wait until you walk away to leave, it takes practice to get to that point, but it definitely is do-able.
Like others have said with the bucking, ground work. No real help here. Lol. Havent had that experience thankfully.
Hope it turns out alright for you and your girl!
