[behavior] [advice] I fear I'm becoming abusive towards my 3yr old

In the past few months I've found myself in blind fits of rage towards my 3 year old son. This isn't in my personality to be like this and I don't know how to control it. I'm a stay-at-home dad during the day, working a few hours a week in the evenings and the weekend. He goes to daycare 3 times a week, half days. (Sorry if this is rambling ... he woke everyone up an hour and half earlier than normal, including a 7 month old we've struggled to get to sleep at night.)My son is energetic, to say the least. His grandparents call him the tornado. When your kid is playing in the park, mine is running around the full sized running track. (Not an exaggeration)This energy will manifest itself in bursts of energy like that or in emotional highs and lows. He will explode into fits of being upset over any little thing. I've tried the 1,2,3 magic book and some of what I've read in Love and Logic.When he was 1 it was discovered he had higher than accepted lead levels. High enough that the city sent someone to our home and our landlord had to have the entire place specially painted by a lead specialist. He didn't attempt to speak until less than a year ago. He was part of a program that sent 3 different specialists to our home -- one for speech, one for developmental and one for occupational therapists. He's been accepted into early preschool because the school district feels that if he started later he may be left behind.He doesn't, as the occupational specialist said, "transition well." Meaning, it is challenging for him to go from one activity to another without blowing up about it.These highs and lows have worn me out and now I'm becoming physically aggressive towards him. I can literally hear myself in my head say things like, "If you're gonna cry, I'll give you something to cry about."In the past, and before our baby was born, I'd go running with him in running stroller. This was one of my favorite parenting experiences. But with the baby and him, I'm so exhausted and the stress just builds until I lose it.I don't know what to do. I don't know how to make an environment he flourishes in and one where I'm not coming undone.This is a throwaway account because I'm so embarrassed about my behavior.
