DQ, Fighter, Mistress: Thanks, dear friends, I appreciate the hugs.
I made it through alive. Tthe blood drawing itself was very quick, very painless, and I bought myself a new betta on the way home. ^_^ Now I just have to wait for the results of the lab. Doc said he'd let me know even though he's on vacation in Hawaii.
Creat: I'm really so sorry you've had such awful luck with fish. I can tell you it's nothing you're doing. You take good care of your fish. I think it's one of those things where all your bad luck piles up at once and then you'll have a stretch of good luck for a loooong time. I suggest you sterilize all your tanks, sun dry them, put them away, wait a few months for the grief and anger to pass, and then get a new betta. Just don't wait too long, we'd miss you on the forum.
Platylover, I'm so glad it worked! You were able to prove you could handle the situation like an adult and that must have impressed your dad. I know it's not easy holding on to your temper when things are frustrating but yay for you, you did it!
BettaMiah, aww, I'm sorry your Yuuki's tail got messed up. :( Lots of AQ salt, clean water and TLC should help.
