Sadness overwhelmed me

He promised to msg me, but he didn't.
I'm sitting here alone in my room , thinking about what i have been through recently.
I feel abandoned, abandoned by the world.
I don't like this feeling, I really don't like this, it's eating me up from the inside...

I missed him a lot, but right now i just don't feel that he misses me that much.

I'm sad and down, needed someone to accompany me, but his friend somewhat seems more important than me....

Tell me what to do.... I really don't know how
