I have the same issue. I see a therapist. It seems that everyone thinks medication is the only solution to PTSD symptoms. For me, I see more long lasting results with therapy and other therapeutic ways of life than I ever saw with medication. The side effects of medication are huge.
I am very anti-medication for many reasons. I would prefer to use natural remedies and treatments as opposed to endless ups in medication. I do therapy. I haven changed my diet. I see tremendous results from changing the foods I eat. I stay away from too many stimulants including too much sugar. I exercise. I want to try acupuncture or vitamin supplements to help it. It doesn't make sense for me to be dependent on medications. There are many different treatments that are natural which I simply have not explored. If people have gone into remission from cancer using natural remedies, I do not see why PTSD could not be approached the same way.
If and only if all of these do not help with my PTSD, I would reconsider medication. I want to have kids with the right person. How does one approach getting pregnant or breast feeding if the blood is filled with medicine? I don't see medication as a solution to my PTSD. It is only an aid for me.
That being said, medication is a solution for many mental illness, but there are ways to recover from trauma. If our symptoms are truly trauma induced, then there are ways to undue the affect that has taken place in brain chemistry. I am not one to take tons of medication in the first place. This is my disease. I want to try to cure it naturally. I feel like the therapists and other professionals in my life need to understand that I get to choose my own treatment plan. It should not be the other way around.
I do know, however, that depression does not go away. For me, the depression is never independent of anxiety, flashbacks, and dissociation. If I was just depressed, I would treat depression with medication.
I battle agoraphobia sometimes. If fact, I didn't leave the house but two times after I was raped for 9 months. I get scared about being out around people. It is easier now than before. That was never the case before I was raped. I had to be out and about before. Now, people's capability of being so very evil makes me fear them. These are thought distortions. I just don't see how medications will ever solve them.
Every person is different. It may very well be that your therapist is completely correct. If he/she truly thinks you suffer from depression, zoloft may be the best solution. You could also see about medications that would best suite your desire to have another child. There are options. Doctors too often do not want to experiment with changes in medications. You have to get the right dose to ever get better.
