Somehow I think if you seeking 'that' person to fully understand you, @creative_writer , you may be disappointed that you won't find them.
As ideal as it sounds, I'm not sure if it is achievable. Please correct me if I'm wrong. I spent years looking for 'happiness' and that one person who would understand me... I later learnt that this was an unattainable goal for me.
Seek to be comfortable in your own skin. Seek to be content with yourself. Seek to enjoy your own company. Then, things may 'fall into place'.
This is my thinking. From being chronically suicidal, depressed, and continuously self-harming, I couldn't believe I found life. To this day, it brings an overwhelming gratitude to know that I'm able to live life. I honestly never thought this was possible.
Hence, I know things seem dark right now, but I want to share hope with you. There IS hope.
