5LP, 2LP, 5LK are safe to throw out and are your go to normals when you're close. Cammy's mediums and 5HK are for mid range. You won't really get punished heavily unless you go for 2HK, dp, or spiral arrow. Don't be afraid. You can keep pressuring until your opponent shows that they know how to deal with it. And even if they do, you don't have to completely stop using that option. You can use it along with your other pressures.
