You’re sooo worth it. You were never inadequate to begin with. Sometimes people do very shitty things to other people. Maybe you were a victim.
The events or circumstances that surround you do not have to define you. The thoughts you have are only thoughts and they do not have to control you. Let them go if they cause you any harm. You actually do have that power to do so. Please find the strength, courage and believe in yourself.
Healing can happen. Just ask anyone who once found themselves in a similar situation. As humans we have the ability to be so resilient. You’re no different.
