Hello & Welcome, Lima01. I have no personal experience with hypnotherapy. I have read blogs on PsychCentral (
one example) that mention hypnotherapy being of possible help for depression.
Grieving any kind of loss is difficult and cannot be forced into an arbitrary timetable. I'm glad you are getting help.
Please keep posting.
