How do you talk to yourself ?
The number one indication that you're not your own 'bestie' is negative and or abusive self talk. How we talk to ourselves not only reveals our relationship to ourselves it also sets up how we take care of our health, our home, our careers, relationships and...pretty much everything.
How we talk to ourselves is where our internal world forms our external world.
The tone with which you talk to yourself, as well as the actual things that you say to yourself, will tell you pretty quickly how you feel about yourself. Bring some awareness to this and you will find that you are talking to yourself on some level much of the time. So, listen to what you are saying.
Are you being supportive and patient to yourself?. A good way to determine this is to ask yourself if you said the things you say to yourself to your best friend would you still be best friends.
If the answer is no, you probably have low self-confidence.
