Too Much Hope

... Too much hope
Ok.. It is fine to hope, but to hope over the top is just a bit over...
I hoped that everyday my friend and I would meet after school along with my other friends.
Since this happened everything, I didn't think there was a day without it...
Ok fine.. today was the day...
It is 100% my mistake because I was waiting for them inside the room along with another friend.
At the same time, I didn't know that my friend along with my other friends were outside the room.
I should have checked outside to see if they were there, but I didn't.. since i thought they would come in, which they didn't in the end since I guess its because we got kicked out from the room for the past 3 days due to testing.
Yes its my fault, but what surprised me was how hurt I felt when I saw that friend leave the school.
I am aware of how i felt for them, but i didn't think that I have put so much hope into it that even a small mistake would hurt me like that.
I already promised myself many times that I wouldn't put too much hope into 1 person, but I failed to do it once again.
Even if I were to say to myself that I wouldn't put my hope in them again after this because I know there would be another misunderstanding again and I would get hurt in the end due to my mistake, I don't know what I want to do...
To put my hopes in them again, even if it wasn't there fault but mines.
To tell them that I was waiting for them inside, even though I don't want them to know how I feel.
I don't know what to do anymore...
Should I just continue on hoping? I know nothing more will come out of it.
Do I stop hoping? That will just change the way I act and it would get awkward.
I'm so confused... So tired of my decisions. I don't know what I should hope for anymore...
Cause if I hope again, I know I would get hurt like this again, so what can I do?
