I sometimes fabricate things or lie to make me seem more interesting to myself. i am aware it's not true. am i a pathological liar? is it my ocd?

Lying: is a bad habit, PERHAPS pathological or perhaps not. Break the cycle by stopping yourself mid-sentence when you become aware of what you are doing. If the lie is out, tell the person you exaggerated. See a mental health professional to see the extent of this and if treatment is needed. Congrats on being aware of this. As you get free of this behavior life can get better. Peace and health.
