Love yourself the way you wished they did. Be your own upgrade. Take yourself on dates. Take the time to understand your triggers, process old emotions, shift limiting beliefs, release energy blocks, look up at the stars, follow your dreams, meditate, and hang out with your soul.
Never let other people determine your value. You can be the whole package and still end up at the wrong address. When this happens, the receiver will not value you because they haven't learnt what is needed to fully appreciate your presence.
Shout out to all the people who grew up with emotionally unsupportive parents and have to hear other people talk about how supportive their families are while you're guiding yourself through life. If nothing else, some experiences just teach you how to be there for others.
