i don't know what i am doing wrong

I don't even know how to start! DS is 6.5 mo old. All was fine till the beginning of this year. He used to drink well, sleep well, was in a good routine, used to sleep wherever and however when sleepy, not fussy at all. Fortunately, did not have major problems or issues apart from initial couple weeks and growth spurts and the fact that he gets bored pretty fast and needs to be continuously entertained! He left bottle when he was 3.5 mo and has not taken that yet, despite many attempts.

Now, it seems like those times never existed! I started pureed fruits and veggies one month back along with some finger food and then moved on to cereal, he used to enjoy it. Now he doesn't want it! As soon as i try making him sit in his high chair, he throws a tantrum! And every 2 hrs he wants b00b. It's just impossible to put him to sleep. Neither will he settle by himself nor will he want me to calm him down. I know when he is tired, he pulls his ears and kind of rubs his eyes, so i lie him down, try to tell him a story or pat him or something but he just keeps kicking and punching and becomes more active. Even after massage and bath, he takes a lot of time to settle down, that too not without assistance. I have to distract him, rock him, or do whatever to put him to sleep to avoid over-tiredness.

He goes down by 8, waking almost every 1.5-2 hrs, and totally wide awake by midnight and won't sleep for next couple hours. And this time, he wants either me or DH to play along, if left alone in his cot he cries. We are sleep deprived beyond imagination and irritated all the time! I'm not an advocate of CIO, but still gave it a shot over last 3 days without any success, rather DS is coughing since last evening.

I don't know what to do, I don't know what not to do! I felt so helpless, lost last night that i broke down. DH didn't know whom to console, crying DS or crying me! :(
