I've already failed as a parent

Approximate schedule before last Wednesday:
Wake up at 7:45am. Naps at 10 and 2 which she took in her crib. Only fussed for a second and then fell asleep. Adorable and smiley during the day. Barely fussed at all, if any. Bedtime at about 6 so that when the time change happens this weekend, it will be 7. I was planning ahead.
She was great sleeping through the night waking up once or twice and then going right back to sleep.

Last Wednesday to last night:
I was trying to get her to go to bed on her own. I would put her down and she would cry. I would check on her every 10 minutes to reassure her. It started to get better, then it got worse.
During the day she was always tired. Naps were messed up. She wasn't smiley and was always rubbing her eyes because she was so exhausted. Last night I put operation "cry-it-out" on hold until she is older. I went and got her and held her until she fell asleep, about 10 minutes. Then she woke up at 2:45am. I fed her and put her back down. She cried and stayed awake until 5am. Not normal. I have totally wrecked my baby.

Today, Wednesday, a new day:
She woke up at 8am and I just put her down for a nap. She fussed for two seconds and is asleep (I think). I will put her down in her crib tonight for bed and if/when she starts to cry, I will get her. I will hold her and rock her until she falls asleep. Then I will walk her up to her room and put her down. Hopefully, I will get my happy, non-exhausted baby back.

I've already failed.

UPDATE: Not asleep for nap. Screaming.
