Re: No friends :'(
I am so sorry to hear you have no friends. Holding on to such hurt and anger to your last friend is very detrimental to you. I would try and put that behind you and start with a new and positive attitude.
To have a friend is to be a friend. There are so many people in this world that would love to have friends, you have a great pool to draw from.
How have you found friends before? Do you have any regular outings, interests, or hobbies? Do you work of go to school. These are the usual places we find our friends, as well as in our neighborhoods.
Do you know why you last friend decided to spend her time with your sister? Did you have a falling out? Finding out what caused you last friend to stray away might be difficult to swallow, but it would give you and idea of what went wrong. A bit of self realization sounds like it might be in order.
What ever you do, try and not get down on yourself, Just pick yourself up and get out there and have some fun. Enjoying yourself if the best way to attract others.
My best to you...
