I get the feeling, I get that it recurs again and again, and you might feel that you are "doomed" to live as a loner. However, you can't trust those thoughts.

Do you ever stop and consider, why? What does it mean to say "you should live as a loner"? Are you saying that nature designed you to live that way? That your biology predisposes you to this feeling, and therefore, to a loner lifestyle? A great deal of evidence from neuroscience which demonstrates the brains plasticity directly contradicts that perception. Fact is, you are NOT What you feel. In truth - and I know this might scare us - we really do have the final say - the veto power - with what comes in or goes out. We get to choose our thoughts, and the feelings we want to go with them.

Indeed, it's a difficult job trying to navigate this road. Were bumped all the time - "she responded to me funny", "he never calls me back", "nobody likes me", with experiences that suggest thoughts and feelings seemingly continue to occur. But I've discovered that it's really all about how we think about our own thoughts. Like a physicist observing his experiment, our sense of self and identity is INFLUENCED by our self observations. For example: If I see myself acting insecure, or find others not taking an interest in me; after observing this, there's a choice we can make: it can either be seen as a reflection of who we are, or, it can be a mere phantom of our current state of mind. The more you think this way, you learn to see things from a depersonalized perspective. This allows you to smoothly transition from one state of mind to another, without the interfering "i am not worthy" thoughts jutting in.

I know this might sound abstract, but it really does adumbrate the way problems arise in our minds, and how we can best get rid of them.

The brain is plastic. We each have the power to choose how we want to be, and how we want to see ourselves. The brain will follow suit after time. You just need to believe.

If you want some encouraging books to read, check out Jeffrey Schwarts: the mind and the brain (which elucidates the scientific basis of how the mind imposes change on the brain), and "You are not your brain: the 4 step solution". Also read "rewire your brain".

Good luck, and please, continue believing in yourself.
