Wah, in 4 posts you alreadi found a solution to your depression.
That's good. For most teens, friends are more important than even
their own family members. They feel a need to 'belong', to be
'accepted', not to be 'ignored'. These feelings stem from a lack of
self-confidence, being afraid of rejection, being alone, or being
outcast.
Friends come and go. New friendships are formed as old ones die. It
is not the number of friends you have that is important. In fact,
those who have 'many' friends are actually the insecure type. Good
friends are actually very few and can only be counted on the
fingers of one hand!
The important thing is yourself: Are you friendly?
So, don't get depressed over such a small emotional issue. There
are so many interesting things to learn, to do, to achieve, to
read, to write, to help than be emotionally affected by one friend
who didn't want to talk to you. Its her perogative. Don't be
possessive. Talk to me!
