Calm your emotions first so you can think straight.
One of the characteristics of a relationship that has not matured yet is the constant need for each other, being pulled and torn by emotions running high and constant break ups and reunions.
Try and get over your neediness. This seems to be a central issue in your life right now. Do you feel that way? Ask yourself, Do you feel controlled by your emotions all the time?
Make a plan for yourself. Think of the person you would like to be, the qualities this person has.
Make steps towards this goal. What can you do to start becoming this person?
The best advice I ever got when I was mad about relationships and boys was "Fix yourself first and you will see, you do not need to look, they (boys) will come to you, they will flock, you will even be in a position to choose"
