I am worried that they are right and that I am just too useless to be a solicitor

For the first 4 years everything was great. So I messed up 2 files by not filing documents in time, because I was distracted by bleeding and/or dazed from meds. After Jacob had a breakdown and left, I inherited all his files. My husband and friends think I need to quit and get a new job, or at least have some time off.

This isn't like her.... Usually she always asks what's wrong... she told me many times she's there to listen to me when I need it.

So I message my friend and I told her I was having a rough time and I needed to talk to someone.

Claudine:
She'll sometimes talk trash and will try to be little me and one day I brought up how she was a year ago and told her what happened to what she was saying before, that she never talked all that trash when she was all over me.
