Hi Lea,
I hope you find peace in your heart.
I have been through various scenarios (deaths, breakups, jobless, etc.) that made me feel lonely and feel worthless. I am going through one at the moment. Maybe I can understand your feelings and relate to your situation.
What I do when I am in such situations is, to work towards getting myself better. Either physically or mentally or through education or whatever you think that can add value to your life. That way when I look back I am able to see the growth I achieved as a person and the transformation I witnessed in the process.
Feeling lonely and helpless is terrible. No one wishes to be there even if situation forces us to be. But when we cannot change our situation I believe we need to work on us to face it and eventually to become a better human being. I always remember this quote to reassure myself:
“Try not to resist the changes that come your way. Instead let life live through you. And do not worry that your life is turning upside down. How do you know that the side you are used to is better than the one to come?”
Take care Lea.
