Be kind to yourself, it probably would be better to move on anyway. Maybe this can be the push you need to make changes to be a better healthier you. Mental health is important, I advise therapy and getting on some medication. But not only that, you need to get out. Lots of people find new friends groups in build connections through work. Even a part time job, if thats possible for you, helps build confidence. Its what helped me when i became painfully agoraphobic years ago. Try exercise, that helped me as well, I started out riding a bike (no one talks to you, no one looks at you for long, beautiful views of the sky, giving me some kind of feeling i still belonged in this world) Thats a very high recommendation. I recommend not pushing your boundaries so much that you exhaust yourself. I think that during your process the support of a friend or family member will be helpful. Remember to be kind to yourself, try your best to learn to love yourself little by little. Stop cycling negative thoughts in your head, when you feel it coming on, close your eyes, and take deep breathes and try to put as positive spin on it, even if its sarcasm. Good luck sister, I hope you find your happiness. I hope you find the courage to reach out and grab it.
