I lose 100-130 strands of hair a day normally. When I play with it much, I end up in the 150-200 range. Is it normal?

Be sure to review your whole story with your dermatologist. If you wash your hair daily it could be a bit excessive. If you shampoo 2-3 times per week it certainly could be within the realm of normal. If you are worried, please see your physician for blood tests and further careful review.

This is probably nothing to worry about- everybody sheds as part of the natural cycle of hair growth. Unless you are noticing a difference in thickness/density of the hair still left on your head, I doubt you are losing your hair.

Hair loss of 150-200 strands is normal in daily life . There is no need to worry about .İf daily loss increase to 300 or more , better to visit a hair expert 

When you are losing hair, combing or brushing it more just makes the miniaturized hairs fall out faster.  see a doctor and get a diagnosis
