Sounds like you are in a place most of us have been more than once. It also sounds like you are at least self aware enough to recognise your emotions. Something that works for me is to regularly check in on myself and label what I am feeling ... 'this is sadness', 'this is stress' 'this is anger I am feeling'. It seems the minute you label it, it either goes away or becomes less prevalent. Do this each hour if you can manage it. When the negative self talk comes like arguing with past or fearing the future, you need to set is aside. Tell yourself 'I notice I am having feelings of anger about someone who hurt me the past, those feelings can stay, but I'm not going to engage with those feelings'. DO the same about the fear and unfounded exaggerations about the future. Keep bringing yourself back to right here and right now, and be aware of what you feel. You will be surprised how over a few short months things work out much better
