what you said was right, you just need to plow through it. SP is definitely scary (the first time I went through it I felt someone grab my foot - I just couldn't continue after that). I think some people's problem is their outlook. Don't think you need to get through it all the first time, just go a little farther each time until it seems normal to you. Don't try to change what your body is doing, just go along with it and you should be okay! Hope this helps?
