No friends - lonely

[Pink grapefruit]

I am in late 40s and have not been able to make close friends since I moved from another country to Australia. It’s been almost ten years. I always feel I am not good enough and cannot have a confidence to start conversation with strangers. I feel worried that I am going to be alone for the rest of my life.. could anyone, especially who are and were in the same situation, please share the tips to overcome this? 

I have my family but I would like to have friends to chat with or meet with.

Thank you, Mark Z. I am actually surrounded by some people at work who are trying to find fault with others to make themselves look better, which make me depressed. I would like to have healthy relationship if I can make friends in the future.
