This is actually an incredibly good point; although counterintuitive. However, OP, you should focus on your advantages and why they make you fucking awesome. At this point, I am not sure if you are being a friend to yourself. It is possible that your ethnicity, your accent/lack of it, your assets are hindering you from making friends with some people. However, this is a planet of six billion people. Find out what makes you truly happy and make peace with yourself. Seek out things that make you happy. At that point, you will attract people around you who truly enjoy your company. Be patient. Superficial relationships are easy. Making really good friends/strong relationships is incredibly hard. For everyone.

A sensible suggestion among many canned responses.

I would say "get used to being alone", though. If you are OK with being alone, you don't feel lonely very often.

Reminds me of a Bukowski poem:

  there are worse things than
  being alone
  but it often takes decades
  to realize this
  and most often
  when you do
  it's too late
  and there's nothing worse
  than
  too late.
