Is Being A Parent Really Hard? Or Do I Have The Most Difficult Child In History?

I am a lost father. I hate to use cliches, but I am at my wit's end. My son is 5 months old and has been a terror since birth. I know. I know. Most of you who have had difficult babies are probably thinking you know what I'm going through. I beg to differ and challenge anyone to prove that their baby is worse-behaved than mine. lolHe started by sleeping for no more than 2 hrs at a time during the night. Now, at 5 months, he still has yet to sleep the night. In order to quell any thoughts that I may be utilizing poor strategy in regard to getting him to sleep, I will tell you all what I do. He usually gets tired around 8 pm and goes to sleep. I will "wake him," so to speak, at around 11pm to feed him. He rarely fully wakes up, though. I give him 7 oz of formula, mixed with 4 and 1/3 tablespoons of rice cereal. I warm it up as well. He still wakes up at 4 am. He wakes up for good around 7. This I have become accustomed to. I feel he won't be doing this much longer, and I can deal with once per night. Any advice on getting him to sleep through the night will still be appreciated.By far, his favorite activity to do throughout the day is cry. Yet, I don't feel he has colic. He appears to be either spoiled or restless. Yes, sometimes he is hungry or needs to be changed. Yes, sometimes he is simply tired. I still wonder though, is it REALLY necessary for him to SCREAM as a sign of sleepyness? But I digress.Most of the time, he seems to be crying for one of three reasons. 1.)Just because. 2.)He's sick of doing whatever he is doing. 3.)To piss me off. My son has the attention span of well, a baby. lol My best friend has 4 kids. He recently had twins. His twins will sit in their car seat for long periods of time and simply sit and stare. They will fall asleep in their car seats, and they sleep through the night. My son, as previously mentioned, does neither. He feels the need to "alert" me of his sleepyness, via screaming. He also wakes up through the night.He won't do ANYTHING (except cry of course) for more than 10-20 minutes at a time. He won't play with toys. He won't take pacifiers. He won't watch TV. He won't sit in his car seat. He won't play with his activity games. He won't sit in his swing or bouncer for more than 30 minutes. All of these activities lead to crying within 20 minutes. The crying only stops when I pick him up. Needless to say, I can't walk around and carry him all day. I rarely find time to cook, nap, clean, or even use the bathroom. Sometimes he cries just because I left the room. The only reason I can even type this is because he's asleep now, after an hour of inconsolable crying. He seems to grow tired of doing anything, then cries to let me know he wants to do something else. He constantly needs to be entertained. He will SCREAM, as if he's pain, then become silent once I pick him up. It's flattering and angering at the same time.I am riddled with guilt as well. His behavior and my personality don't match. I am a logical thinker. For me, every effect should have a logical cause. His behavior is illogical. I can't figure it out. He appears to cry for no logical reason, and it INFURIATES me. I get so angry. I would never do anything to him, but I have a bad temper and little patience. So he can upset me very easy. I love him so much though. So when he's calm, I instantly feel incredibly guilty for being so angry at him. After all, he IS just a baby. To top it all off, his mother (as well as my friends) act like I'm over reacting and that tons of kids are this way. Really? REALLY!!??! I have trouble believing all parents go through this. I have personally seen and talked to several parents (friends and family) who have had things much easier than I do.Please forgive the length of this, but I needed to vent. I don't know what to do anymore. I never thought I could "meet my match" in an infant, but it appears I have. I'm out of answers and ideas. I think I'd be happy if someone convinced me that their baby was as bad, or worse, than mine. Then, I wouldn't feel so alone in this.
