Jade, yes... reading can become too much, for example why I posted [DLMURL]http://www.ptsdforum.org/thread556.html[/DLMURL] so that members and readers know that they must balance out their exposure here, and in fact to any information in regard to trauma and healing. Too much at once can be a bad thing. This is the same reason why a counsellor has appointments a week or two apart, so the brain is allowed time to process, get depressed, get anxious, come out of it and recover before hitting things again. Reading here will be a trigger, no doubt about it. Reading here will cause anxiety, especially reading information specific to your trauma, or that raises traumatic memories. Opening pandoras box is a decision you must make, and if you choose to open it, there is no going back until your through it.
Addicted and dependent? One in the same. If you look within the dictionary actually, addicted is used in dependent, quote: dependent - addicted to a drug.
There are three main categories, being use, abuse and dependence.
Use: To take or consume; partake of: She rarely used alcohol.
Abuse: To use wrongly or improperly; misuse: abuse alcohol; abuse a privilege.
Dependence: A compulsive or chronic need; an addiction: an alcohol dependence.
From the dictionary definitions above, you can clearly see the difference, and being dependence uses addiction as its equivalent meaning.
