Sounds like you have a lot going on right now. I think it is "normal" to feel overwhelmed and unpleasant with what you have happening. And, when we are stressed, it is harder to respond well to additional stresses but that does not mean one is failing, that just means there are a lot/too many stresses going on right now! Too, being sad/depressed/anxious can bring up more sad/depressed/anxious thoughts. Just keep putting one foot in front of the other and you will get somewhere less stressful. I wanted to cry myself to death and told my T that and she explained it is physically impossible; one can cry for a long time but not forever/to death. Eventually our body takes over and rests us. When you "slow down" and don't seem to be making much progress, thank your body for caring for you, for slowing you down and relax in it for a bit. The struggle can be picked up again, when you are more rested, it isn't going anywhere
