Need support, bipolar or boederline

Hi there.. I don?t know exactly what I?m struggling with. I have diagnosis ?bipolar II? but act mostly like a borderline. My doctor admits that it might be true, but she is not sure. My first visit to psychotherapist was 3 years ago. I used to think that my main problem is OCD but it was just a minor symptom.
I?ve been suffering from anxiety, mood swings and depression for 12 years. My interpersonal relationships are stable, especially friendship. But romantic relationships are the problem. I hardly get along together with someone. Now I?m going through divorce after 5 years of marriage. My main problem is ? I?m an ?emotional alien? to my dear people. Especially for my family. They claim that all my problems are just fantasy, because I have no real problems. They don?t accept the main part of my identity. I?m simply wrong for them. I?m sinking in guilt and frustration. I fail to leave normal life. Sometimes I act immoral because of terrible pain. I have the greatest fear of abandonment. I have only two friends who understand me.
Please talk to me, I desperately need to talk to someone who shares the same problems. Who are also like a ?ghost? in the world of normal people.
