How can someone with an avoidant personality overcome that and lead a normal life?

Hello doctor,

I am a 29 year old male. I recently took an online psychology test and found myself to be a dismissive-avoidant personality type. I took the test because everything is not fine in my life and I want some solution. I am single, and highly educated, managing my own business and live with my parents. These are the details about my life and problems happening. Personality: I am an introvert and do not like attending social or family gatherings. The last time I attended any marriage party was twelve years ago of my brother's. I do not have any friends now and had few friends during college. I do not like waiting in line, crowded place or traveling much. I like to spend time alone, reading, listening to music, etc. I work from home alone since my nature of work is online and have not taken a break from work in the last five years. I am a kind of person who wants control, freedom, independence in life, very practical and live in the present. I hide many personal feelings and do not share them with others because for me it is a private matter. I feel like I trapped myself in a self-imposed social isolation and do not know how to come out of that. Family: Mine is an upper-middle-class family. My elder sister and brother are married and stay outside. I am the youngest of the three and live with my parents. In childhood and adulthood, my relationship with my family members was good. As I got older and learned the real meaning of life, it feels like all the relationships are transactional in nature. They care for you till you have resources and once your money is over none care for you. I know parents care for you if you care for them and same is the case for siblings. Frankly speaking, I do not have a good relationship with anyone in the family. They do not like me due to my nature of living in own world and avoiding family gatherings. Relationships: I had many failed relationships in the last ten years and most of them were long-distance. I have not yet gotten over the pain of my past breakups and some pain is still inside. It feels my heart is broken, but I am smiling to make myself and others happy. Some relationships did not sustain due to my partner not agreeing, family not agreeing, incompatibility in choices, etc. I moved from one broken relationship to another just to forget the breakup pain. Now, I am cold to relationships, have commitment problems, and feel like running away from responsibilities. I have taken decisions in life thinking about my career or goal without thinking about my partner's feelings and the effect on the relationship. I am in another relationship now and thinking of marriage, but somehow my past breakups and personality issues are causing a problem. These are some queries I need your help with. Is there any problem in my personality or life? What is the solution to problems in my personality or life? Am I having a dismissive-avoidant personality issue? What is the cure for dismissive-avoidant personality? What other suggestions would you like to give me? Looking forward your reply. Thank you.

Hello doctor,

Thanks for the reply. My personality issues are causing a problem with my family and relationships. Also, I feel suffocated by it. There are some points for which I need a more detailed reply. How can someone with an avoidant personality overcome that? How possible will it be to change the personality in my case? Can you live a normal life in spite of having an avoidant personality? Can I have a successful relationship in the future? Does avoidant personality issues change automatically after marriage?
