I’m sorry you’re feeling so bad and I understand because you have taken a very big step forward and that’s not an easy thing to do. Sometimes it leaves you feeling like you’re between a rock and a hard place, damned if you do or don’t. We are creatures of habit and even when they are bad for us we still tend to go back to them only because they are familiars, making changes in life are always big steps but it helps to keep in mind what and why you wanted to do so. When you leave a bad situation it feels good at first because you accomplished something however it takes time for you to start moving forward and that is when you start looking back at what you left, naturally you start thinking that things weren’t all that bad because we tend to forget about the bad stuff, this is when you start doubting yourself and what you’re trying to accomplish. It would be wonderful if we could walk away from things easily and then start on something new but it doesn’t happen this way. If you’re confident that you’ve tried everything possible to make your relationship work and it still doesn’t work out then you owe it to yourself to keep going forward. I hope that you have some family and friends to talk with, therapy is helpful but it’s not always easy to find depending on where you live or financial circumstances. I would like to add that I have been where you are and even though it feels so hard to keep going, it will get easier with time, one day you will just know that you’re doing something right for yourself and everything else will come together,
