I put to much pressure on myself

I never think things will go well for me I always think of the worst scenario first I put a lot of pressure on myself I just feel like I'm not good enough I'm constantly battling with myself take yesterday for example I went into my driving lesson feeling confident then I just put pressure on myself and screwed it up I just freaked out and had to stop the lesson I thought I was going to damage the car just little things I always predict going wrong I wish I had more self belief
