I think it gets easier the more you do it. I never used to be able to talk about myself at all, it was only after intensive counselling that i started to be able to talk about myself. To start with it was absolute murder, i remember my counsellor pointing out that i was talking to her but i was sat not facing her but facing the wall instead, it's true i was. Even now i still struggle a lot of the time to make eye contact but i do manage to talk about things a lot easier. It makes a big difference if you can open up and talk with someone, be it a Doctor, Counsellor, Therapist, or a close friend. It takes practice, a lot of practice, but it is very worthwhile in my opinion.
