I was never married so I dont know if this even belongs on this board, but my boyfriend and I just broke up after three years

. it;s only been a week and my thoughts are constantly spinning around the relationship, what went wrong, how i miss him, im pissed at him, im full of guilt. Just last night I had a brief break and felt okay about the break up now im back in the pits again. Is this normal???? How long does it take to get over this and move on???? I am not good at dealing with emotions at all and to have all of these coming at me at once is unbearable.
I feel like im going crazy. Im 26 is this is my first REAL break up. I have always had someone whether it be simultaneously or one one. He was my longest relationship. I have nooo clue how to handle this. I have to keep busy to keep from thinking about him and us and to keep from calling him. He said that it's okay to call, but I dont want him to take it away 6 months from now. I dont know what to do
