Hopefully that gets the ball rolling for everything else then. Always a really good start. As odd as it sounds, try making a list of things you want to do/change and let yourself be emotive when you write it. Keep the list hidden and every so often when you start to feel more like yourself have a look at the list and you can begin to tick things off that you’ve achieved.
There’s that or what my therapist said to me to do was write a letter to anyone/anything that was affecting me be it good or bad. Write any problem down. Take it to a bbq or a fire pit and throw all the pieces of paper in. Suppose it’s symbolic of everything burning away except you because you’re stronger than that which is on the paper.
