Not sure who i am any more

Since I got my diagnosis a few weeks ago,, (aged 51 female for those that don't know me) I'm not sure who i am. I have struggled always, masked most of the time an had catastrophic mental health problems but also raised a family of 5 children got a degree and held a professional job for 20 years untill i became too ill.

I don't know how to be me. How to not mask, I can do all of nothing, mask or curl up in a ball. Stay in bed or up but I'm my nighty or go out and be that ever coping mother/ house wife etc. This is not working for me it messed with my head being the super masked woman, I need to not be her, but how do I be someone else that isn't just a fat blob in a bed rocking.

I'm NOT feeling suicidal at the moment, but there doesn't seem to be a lot of point to it all. 

How do I become me?
