I think that the stresses just become too overwhelming at times and it can leave you feeling very lost. I found it incredibly hard to make decisions on every day things that I wouldn't have thought twice about before. The only thing I can say is be kind to yourself and be patient with yourself. As others have said writing it all down does help you put on paper the thoughts you'd find difficult to voice to loved ones, even if you tear it up later, it just helps to burst the feeling of pressure. Hang in there xx
