How can I boost my confidence and social skills?

Ans: Dear Anonymous,
Two things to understand here:
1. You are an introvert and you are happy being one
2. You are a forced introvert as you are unable to break the walls that you have put around you.

If you belong to the first category, enjoy the state of bliss as is. But from what I gather, you seem to falling under the second category wherein you want to expand your social circle and be a part of activities etc.
Then you have to put yourself out there.
1. Do understand that as much you want to be engaged with like-minded people, even these people will at some point in time think different from you.
2. Do accept people for who they are and that way you will come from a non-judgemental space while engaging with them.
3. Do connect with people who are totally different from you and it will help you expand your mind to be curious about them.

If this is a difficult thing to do...think....What if one of your children came to you with the same problem that you have now? What would you tell them to do?
Also, get into circles on social media that discuss topics which interest you. Join a gym or a hobby class and that is an avenue to make new friends irrespective of gender.
To add more friends, you need to be friendly as well...so open your heart and mind...

All the best!
