I think you are feeling beat up, so here is some encouragement!
You are 16 years old and discovering the word's greatest hobby - how cool! I wish I was that cool at 16. I didn't get into this until my late 30s. I think you are trying really hard to do it the right way and will make an excellent snarent. It's obvious you want what's best because you are here asking for help.
We certainly DO NOT want you to bail on this site because you are feeling attacked. You need us! And your snake needs us. Once you get this stuff figured out it will all be easy breazy from here on.
Now the tough love:
The tone you are hearing is for a reason - you don't have a second to waste in getting these critical elements of your husbandry corrected. Too much heat on your snake can not only cause physical pain and scarring to your animal, but can cause neurological issues as well.
Nobody is chewing you out because they feel like it, or because they are mean spirited, but because this is a HUGE issue you must fix immediately. So that's the tone you're hearing, not mean-ness, but more like a slap to someone who's unconcious. Just a little jolt of reality. Truth is - this is one of the kindest, most supportive resources out there for reptile keepers. You want mean? Join some of the FB groups for bp lovers. (just kidding, don't do that - those people are awful)
I think you've got the picture now and you're making your adjustments. We love nothing more than someone who admits mistakes, listens to advice, acts, corrects, and comes back here with an update on how wonderful everything now is.
