It is good that your mum is speaking to your dad - hopefully he has a much better understanding of what you are dealing with @MDT If he doesn't get it then maybe he needs to be told again - sometimes others in our lives can't deal with their loved ones being in a not so great place and he needs to understand that all this pressure you are placing on yourself is really doing some damage.
I am glad you have you psych tomorrow - will be a good opportunity to discuss some of these things worrying you again too.
