So much of us can get lost in the relationship with others that we can give up parts of ourselves. Do those things again that you once did before you met 'what's-their-name'?
Look in a mirror and speak to your flection as a friend. Giving yourself the advice and support as a friend to yourself.
The longest relationship that you will ever have is with with yourself. Show up. Tell yourself the truth. Be authentic. Be yourself. Love and support yourself.
