If you feel freaked out, maybe doing some research about the new meds would help? Are you anxious because of the different type of drug, or just distressed by the fact that you have to change? I felt scared of taking anti-depressants because I didn't really understand how they worked. I thought maybe I'd be a zombie, or get hooked for life. When I learned more about SSRIs and read posts people had written about the one I'm taking, I felt a lot better about things.
As for the stigma, when I've opened up to people I've been surprised how many have admitted that they, too, have had a need for meds at some point in life. Just today a woman at work was talking about starting anti-anxiety meds and I said, "oh which one? I'm on Lexapro..." - she seemed really surprised and relieved to hear my response. I think the only people who are judgmental are those who are ignorant, and their opinions just don't count. It would be just as ridiculous for me to tell someone with ulcers that it's all in their head and they should "snap out of it" as it would be for anyone to tell me the same thing. I do totally understand the stigma attached to psychiatric issues and anti-depressants. I actually feel a little embarrassed because anti-depressants seem to be so POPULAR these days - I don't want anyone to think I'm just jumping on the "prozac bandwagon" because I just want the easy fix of a happy pill.
I'm really glad that you met with a psychiatrist. Since this is their specialty, it only makes sense that a psychiatrist would be able to best work with you on your meds. Let us know how they work out, and don't be afraid to ask from help from friends and family as you make the transition, and also when your husband is out of town (my DH travels for business so I know how challenging and tiring that can be!).
