Why fight the feeling? You know you're worth it! Now live it and make your dreams into a reality. You should know your worth. Start making calculations. Whenever you're down, analyse how you got there. What made your thoughts spiral into the downhill pattern they got to when you thought in a negative manner?
Know thy self. For if you don't and you expect others to "get it", no one will ever get it. YOU need to get it. Know what you want in life, ask the universe to show you the way. Ask those in the spirit realm to guide you or send you a sign. They are all out there. Now you just have to listen and know when a sign comes, and that it was meant for you. Do not doubt the answer. For if it is an answer you didn't want to hear, it was because you needed to hear it.
Know what journey you wish to take your life in. Know which difficulties you need to work on. Make a list, and be ready to know. You are the greatest chance there is to living a truly fulfilled life. Now you just have to reach out and ask for help. Think it, know it, believe it. You know you deserve it. Stop the doubts, and don't give up until it has been achieved.
Belief in oneself can allow the tallest mountain to be within reach. Once that mountain has been reached, never forget the struggles it took you to get there. But most importantly, never forget who you met along the way. You met your true self! Know thy self...
