Exhausted

It was a bad Night last night and I feel so guilty. I am just so exhausted and need sleep but just not getting it.

I went to bed early but Tyler woke up crying a couple of times. He didn't get of bed which was good but still woke me up.
Little Blake woke at 1:15 for a bottle but he is in the habit of having awake time.
What am I doing wrong? Tyler would just have his bottle and go back to sleep, Blake nope. He is awake every night and its a fight to get him back to sleep. At 3am i ended up giving him another bottle and he finally settled.
What upsets me is in that 2 hours I get so annoyed at him. I know it's not his fault but I can't help it. I just want to go back to sleep but he just won't.
I only use a tiny night light, I don't talk or engage him but he still wakes up.

I don't know what to do to correct this. Night time is for sleeping! And this is what I start saying to him as I get frustrated. I just hate that I get frustrated with him.

After he finally went down to sleep at 3:20 Tyler woke at 5 crying so I went in and had to fully change him as yet again he wet through and gave him a bottle and he slept till 7. Little Blake only slept until 6.

I know Blake is going through a growth spurt but surly they don't last this long. It's been nearly a week. He is also only cat napping during the day. He was such a good sleeper and is now just crap. I know things can get disrupted when they are sick but comeon!
30-40mins naps that's it. He is sleeping like Tyler used to. He just doesn't self settle anymore. Even while he was sick I still put him down awake but its that refusal to settle when he comes up into the light sleep after 1 sleep cycle. I don't know how he broke out of his normal routine. I am going to try a new technique and leave him in his bed unless he is upset. He needs at least 2 sleep cycles before I will get him up.

At what point will I not feel so utterly tired anymore.
