A real friend should not be demanding of your time. They know you well enough (or should, if you're close) to understand your life and what is currently happening. Respect is, after all, part of friendship. 

What Ben and mcm said!

Well, my friend, you know I succumb to the same kind of treatment and in spite of all you say to me, I still remain accessible. How these episodes balance out? What's the ratio of good and bad. Will your friend hear you if you express your feelings if for nothing else to vent your own feelings. Of course I'm assuming you keep this person as a friend. It's not me, is it?

Re-evaluate what you call a friend and what you want and expect from a friend  ,,>>>>>>>><<<<<<<<..

Your answer is in your own question. You said she's inconsiderate and self-centered. And what she said to you answers your question. She is not a true friend. She is a user and a fair weather friend.

Sounds like (s)he is a needy person and wants you all for them-self. If (s)he is not prepared to share your friendship and give you space, you are going to be tied down with their possessiveness behavior. Tell (s)he that it wasn't your intentions to set out to hurt their feelings, life just got in the way. Everyone should be allowed to be their own free spirit.

You cant let your friend make you feel bad. She is the one with mental illness, not you. Most likely hormonal leading to more health problems. She cannot make normal decisions . As she gets older and not treated your relationship will quickly be torn apart. Help her seek mental advice and treatment. Chances are she will be a danger to herself or somebody else if not treated. Good luck to you and your friend.
