Bec, do you know much about Remeron? Have you read about its side effects and so on? It is approved for use in medium to severely depressed patients, and also useful for anxiety, appetite problems and insomnia. It is usually used as an "add-on" along with other anti-depressants, are you on other meds as well? The possible problem I foresee for you particularly is that common side effects can include visual hallucinations (if the medication is taken in the daytime) and vivid nightmares. I see those side effects as possibly being difficult for you as you already have PTSD. However, you may not have those effects either. It's difficult to say unless you try the drug.
As you know, I am not a big fan of medication generally, however, it is good for many. Why do you not want to try it? Do you not feel you do not need it? Is it mistrust of the doctor solely? Are you worried about side effects? If you do try it and do not find it helpful for whatever reason, there is nothing saying you have to continue taking it. Perhaps you are simply too stressed at the moment to add another uncertainty to your life? Perhaps wait a week or so until things with Matt are settled and then give it a try if you like? I honestly don't know the answer, simply throwing out different suggestions to you. Take good care.
