When I was younger, especially after my first serious relationship.
But my grandmother(rip) said something to me that played in my ear:
"Killing yourself is selfish. Think about the people that truly love you"
Glad I didn't, I'm blessed and in a better position and the lessons and heartbreaks have made me stronger and wiser.
All you have is yourself. Make yourself happy and learn to say no and fight those voices of defeat.
If you can type on a smartphone or computer, you are blessed..
Think about people who don't even have those luxuries. Embrace the journey and keep smiling OP
