Let's remember that your past experience does not define you as you grow and mature in life, but it serves its purpose as a learning experience for you to not commit the same mistakes that you have done. We are all worthy of being loved, and loving someone else. There may be setbacks and even more struggles to go through, but it's all part of your journey. Never question your self worth to the extent that you no longer feel like you are not enough. Pain, suffering, and even loss can always be a result of every connection you make, do keep in mind that even if you have to go through such, it can only make you better than you were to begin with.
