The controversial striker rejected a £6million transfer to Birmingham in favour of a short-term switch to Parkhead before revealing his feelings about recent events.
The 25-year-old is finding it hard to come to terms with the realisation that he will never play for Newcastle again following his public spat with Graeme Souness.
Bellamy explained: "It's not a permanent move, which I don't think I could have done because, to be truthfully honest, I am still emotionally attached to Newcastle.
"I didn't really want to leave and, the way it has happened, I have found it very difficult because I do love the club and I am not ashamed to say that.
"I couldn't make a decision now and say I am going to start my career somewhere else because I am still coming to terms with life without Newcastle.
"I've set my whole career around Newcastle to try and chase that Champions League spot.
"It is a great club and I am honoured to have played for that football club. I just needed time to get round things and I couldn't commit myself to a long contract.
"I was very honoured that Birmingham wanted me. I spoke to Steve Bruce, who was an amazing person and it was great to speak to him because he is a Geordie and there was no better person to speak to. He understood exactly what I was saying.
"I found it hard to leave Newcastle. It wasn't about signing a four-and-a-half-year contract and the money.
"It was getting my head around the fact that I wouldn't be coming back and playing for this great football club, so this gives me time to think about my situation and see where it goes from there. I just need to have a look.
"This all happened in such a short space of time for me. One minute I'm picking up the 2004 Player of the Year award in Newcastle and then within four days I'm never playing for the club ever again.
"It's such a lot to take in such a short space of time, but I couldn't commit my future to one club so this was a great opportunity for me."
The Welsh international has also been accused of being awkward if asked to play out wide, but Bellamy hit back angrily at those suggestions.
He snapped: "I've never once said I won't play anywhere throughout my whole career.
"I have played 30 times for Wales and played 27 of them out on the wing, and I have played 28 games this season out on the wing.
"It's not a problem wherever I'm asked to play as long as I play, and that's what's most important to me."
Souness also accused Bellamy of feigning injury but the former Coventry and Norwich starlet insisted nobody could question his attitude and commitment.
Bellamy concluded: "I want to win every game I play in.
"I am one of first people out in training every day and in five-a-sides I want to win. If I play keep-ball I want to make sure we keep the ball as long as we can.
"I know a lot of people question my attitude but if that's a bad attitude I am in the wrong game.
"I try and win everything I do and I have never been any different. I am probably a bit too competitive.
"I have such a short career so I want to do as well as I can because it is such a short space of time."
O'Neill was manager at Norwich when Bellamy was a youngster and he could not help cracking a joke at the bad Bhoy's expense.
"Craig was there and I think he was about 12 at the time," said the Northern Irishman. "I believe I just missed him out of the door one day.
"I think he was demanding to be in the first team then, so not a lot has changed."
