Do not stay because you are scared. You'll live to regret it. I'm also terrified but am pushing through. You wont know what's on the other side until you get there.
I think the best advice I've ever received was if your friend was in your same situation, what would you tell them? That seems to help make decisions clearer for me. Hope it does for you, too!
I hope you are doing good today. Reaching out and hearing back makes me a tiny bit better, hopefully, this will brighten your day. Your msg did help me, today. Keep your chin up!
