I am an 18 year old female and since I was young I had noticed I have very VERY bad mood swings that would change within minutes. Sometimes I feel great about myself or everything and in a split second I hate everyone and want to murder everyone. Or I'll feel happy and within minutes I'll feel sad and down. It's extremely hard to explain, but I will try as best as I can, I get this feeling inside where one side is like be angry with everyone and the other side is like be happy and I get so frustrated inside trying to figure out my emotion that my frustration comes out. My family lately has been telling me I could be Bipolar and they've thought so for awhile, but I don't think so. My irritability is out of the window. Any little thing is said or done and I become extremely irritated and pissed off. It can be from my grandfather wondering if i'm hungry and saying "Go ahead and eat an apple" I become irate. He just waved a yogurt in my face and I got irritated and almost went off

It sounds silly, but I feel bad that I react towards my family like this. It gets to a point where no one can talk to me because they become upset with me that I get angry. I need some advice or how were your experiences with borderline personality disorder before you were diagnosed. Is this similar or could this be something completely different? I feel like I am lost with myself. I have a child as well and I get angry or irritated very quickly with her and I don't like that feeling.
I get up from a 5-9 hour sleep and every morning it does not fail, I wake up so irritated and I am irritated for about 2-3 hours then I am okay and happy and give it about 10 minutes and I'm feeling some other kind of emotion.
Suicidal thoughts? Daily basis. I think of different ways to harm or kill myself.
I get terrible headaches (don't know how relevant that is, but just throwing that in there).Due to my migraines that my neurologist diagnosed me with I have recently started a antidepressant that would supposedly help them called Amitriptyline or Elavil. I've only taken it three times, didn't like the effects and seemed to be making the headaches worse and it makes much more irritable
I have posted in the bipolar forum, and they mentioned borderline personality disorder. Did some research online and saw that the symptoms and characteristics fit me much more than bipolar did. Took the borderline personality disorder quiz on this site and got a 49....
