Coco,
Welcome to HealingWell and I am so sorry you are feeling so sad and hurt. I have been in your shoes a long time ago but I can remember like it was yesterday how upset I felt.
It can be so very, very hard to see the end of a relationship that provided you with so many special memories and moments in your life. Memories of your teen years that you will look back on many years later through the eyes of an adult and realize just how special a time it was, even though it never lasted forever as young hearts often hope.
There is a process to breaking up with someone you really cared about. Often it begins with anger and a feeling of inadequacy because you feel that it's all your fault and you did something wrong to cause the end of the relationship. Many times, that's not the case at all and in your case you did not do anything wrong.
After the anger and self-blame subside, you will be very sad. You may even not want to eat and possibly have trouble sleeping. You find yourself crying a lot.
These are quite natural feelings and not a bad thing. It's part of the grieving process and they are your feelings and you have every right to have them and express them. It will help you overcome the hurt and pain if you are able to let your sorrow out and not keep it bottled up inside.
It's not necessary to deal with a break-up all by yourself. That's what your friends are for. Talk to them about your feelings. Coming here and talking with us was brave of you and know we do understand how you feel.
I always remember a song by Incubus : Love Hurts.
I wish you peace and happiness but most of all I wish you love,
Kitt
