It is important that you think about the positive in nursery school then. There must have been a sense of "safety" there that was "nurturing" for you. It is important to consider whatever affected you in a "positive" way when reviewing your past. By focusing on "all the negetives" you may discredit the significant things that you used to become "who you are" that are "positive" in you.
When I went over alot of the upsetting things I experienced in my childhood and at other times in my life, it was important to recognize it, and finally "mourn" whatever had been "taken or lost to me". This is a "part of" the healing process when it comes to reviewing our past like this, or whatever "trama" may be there that we somehow didn't realize had affected us the way it did. When we work through all of these "losses or troubles or lacks" we are viewing it as adults and as adults we have the ability to finally take time to "self comfort, self sooth, and help ourselves finally heal"
from whatever we didn't have growing up etc.
It is important to make sure that by "reviewing" we are not supposed to feel "trapped or unworthy because of what we didn't have", that is what often patients start to think and it is really important that a patient "not" determine themselves a "lost cause". Instead, it is meant to "understand" and "connect with self more" and finally coming to terms with "self" instead of going along with some kind of "void" that a patient doesn't quite "understand".
