That’s really tough. I’m sorry you feel like you have no one to talk to, especially when you’re considering such tough decisions. If it’s worth anything: it is my opinion that at some point it’s ok to be “selfish” and consider the things that will make you a happier, healthier person in the long run so that you can then share this “better person” with someone who deserves it. Take a break, assess, regroup and start over. You got this!!
