they're saying that some plastic water bottles leach chemicals into your drink and produce more hormones. which water bottles do this? how can you tell if it will? i heard if it has the #7 on it, it will leach, is this true?
p.s.: my water bottle is a starbucks coffee one, and it doesn't have numbers on it so i can't tell.

Yes, some plastic bottles can leak some chemicals into the water they are holding but ONLY if filled with boiling water and only into that water(there is no harm through washing the bottle as long as you don't drink the washing water). There is little to no evidence that this chemical is dangerous, especially in the quantities that are released into the water. Even so, it was removed from babies bottles as a precaution as these are filled with boiling water and babies, being smaller, are more sensitive to the possible side effects of the chemical.
In conclusion, there's nothing to worry about unless you happen to be a baby or regularly filling your water bottle with boiling water, then drinking it.

Water bottles that you by from the grocery store or gas station (plastic, you can squeaze them) these bottles you probably shouldn't refill more than 3 or 4 times or chemicals the manufacterers use to make the plastic, start to leak or dissolve into the water bottle. You are right, #7's are also bad and have been known to cause nerological problems in children and teens. If you have one of these bottles, you shouldn't freeze them or put them in heat, this will make the chemical leak worse.
Your bottle sounds like it is a mix of several different products, possibly rubber and plastic. Your bottle might say "BPA FREE" somewhere on it, which means it will not leak chemicles into your drink. As far as starbucks bottles go, I believe they are meant to be refilled and to withstand hot and cool temperatures. These bottles should be considered safe as well.
