Good to hear from you. It does sound like your therapist was perhaps getting into your space a bit. Please do feel comfortable in speaking up when you feel that way. I know I like to maintain some space with most people.
Do you feel the medication is making you feel sleepy all the time or the depression? Wondering if your "asleep(90% of the time)" why he would want to add Melatonin? Does he feel you are not getting good rest?
I am glad you are going to continue on for now and see how you do. Please know I care and I am here for you.
Im with Kitt- it sounds like your pdoc was in your personal space- i wouldnt like it, thats for sure. My P doc recommended Melatonin but i never got round to taking it. IF you do try it, let me know how it works for you.
