uneasy, scare, worry

Today, I talked with my girl friend and found out I feel uneasy when she talked with her friends in front of me. She explained me that I wanted to keep her to myself. It reminded me of my parents because they always tried to do that. When I and my parents talked, it was a bit wierd because they always changed topic. For example, my mom talked about something about my sister, my father tried to speak about TV program to get my attention. Around 20 years old, I noticed they wanted to keep me to either of their side. This made me confused and think they just wanted to talk with anybody. Now, I understood someone talked with my important person made me feel so bad, something anxious.
When I feel scared, I don't know what to do. For instance, waiting for a corkscrew is most hard time for me rather than getting on it. I want to overcome this feeling.
