7．Be Your Own Best Friend
Why would you want to become your own best friend？There are a number of benefits of creating your own support system from within rather than relying on your partner，friends or family to be there for you when you're suffering．We all have it in us to give ourselves what we need，without seeking it from outside．（33）G  Here's how to become your own best friend．
1．Be nice to yourself
The first step in becoming a friend to yourself is to treat yourself like you would treat a friend．（34）E Start by accepting your good qualities，talents and abilities and begin to appreciate yourself．
2．Imagine how you would support a friend in the same situation
Think about a loved one，a friend，a family member，or someone dear to you and imagine that they are in the same situation you are facing．（35）F Then consider how to
best offer help and advice to them．Allow yourself to feel supported，and give yourself what you need．
Write down the words that you would say to your greatest friend and then say them gently to yourself．
3．（36）A
Following the theme of considering how you would help a dear friend，you need to start taking your own advice and putting your own needs first．Do you need a day off from work？（37）C
Whatever it is that you need，allow yourself to put it at the top of the list rather than the bottom．Use these methods to become your own best friend and start being there for yourself!
A．Honor your needs
B．Believe in yourself．
C．A long hot bath？
D．Help them first and then they will help you．
E．That means that you need to stop being doubtful of yourself．
F．Think about how they're struggling，suffering with this problem．
G．Isn't it far better to know how to support yourself in times of need？
