>>36259479My brother my advice to you is to invest your effort into self improvement. Develop yourself into someone worthy of more pride, from there you may be more outgoing.
I would recommend physical exercise, as not only will it make you more physically fit and healthy, the biochemistry of exercise works to release chemicals in your brain that can make you happier and more self-assured.
But any personal development is good though, learning a new skill, following a non-passive interest or hobby, or working on renewing old or lapsed relationships.
I wish you well my brother.
