Hi Bea, Welcome to AC. :welcome:You have come to the right place for help. These folks are awesome. I'm still learning, but have already learned a lot.
All the advice you've received by the AC members is right on. Don't feel bad, we have all been there with water quality issues, loss of fish, mishaps due to inexperience, and such.
I have a suggestion that, so far, I haven't seen. For your water conditioner get PRIME. Made by Seachem. It's at the lfs or Petsmart, Petco, etc. I haven't seen it at WalMart.
I have read hundreds of posts here on the AC, and the consensus is GET PRIME! All the experts here recommend it. It is even cheaper than most of the other dechlorinators.
The ammonia and nitrite you will be having in your tank, until it is fully cycled, is extremely harmful to your fish.
Prime has saved my life, more accurately, my fishies lives.
It removes chlorine, chloramine, but what it does that is HUGE is detoxify ammonia and nitrite for about 24 hours, giving you breathing room to make the big water changes you will need to make.
As you test your params daily, you may find dangerous levels... maybe late at night when you're already exhausted from a days work, you test the water and find you need to make an immediate emergency water change.
An emergency dose of Prime added to the tank, per directions, will give you time to do it the next day. Giving immediate relief to the fish because it immediately detoxifies the ammonia and nitrite.
You still have to do the big water change the next day, but your fish are saved, and you can rest and do it later, within 24 hours of adding the Prime.
Every time you do your water changes you add Prime to dechlorinate, and it also is a safeguard, at least for the next 24 hours, for your fish as your parameters fluctuate until the tank is cycled.
You've been through a lot. Please don't be discouraged or feel like you've let your fish down. You have been led down the garden path by the folks at the lfs. They don't mean any harm, they are just not very knowledgeable, usually, and remember their primary concern is making sales.
These guys here.... I can't tell you how incredible they are.
I even had one of them, mzjinkzd, send me, from her own personal stash of supplies, some veggie and shrimp pellets for a snail I have that was doing poorly. She sent it at her own expense.
These folks are generous with their time and expertise. I sound like a PR person for AC, but I can't say enough.
You will be fine. Anytime you need help, just ask. No question is dumb or goofy.
Please hang in there. (you really do need either a much bigger tank, or rehome the goldies)
Also, though I hate to have to mention this, there may be a time when you know you need to put a fish out of its misery. There is a humane way to do that, that is simple and gentle. (freezing is not the way to go)
I am going to include the link for this. I have had to do this a few times, and it is a blessing to know how to do this in a kind, gentle way, with no fear or stress for the fish.
I have copied and pasted that link into a folder I have on my desktop. I have an Aquaria folder that I have filled with information these guys have posted.
Here's the euthanasia link:

This is a very helpful, detailed article by one of our members on AC.
I could say "hopefully you won't have to use this information", but realistically - you will.
Again, welcome to AC!
