One thing that struck me as I read your post is that you are only 23, and worrying because you haven't met your "soulmate", the person with whom you can have a lasting and meaningful relationship. From my experience, more people meet the type of person that I suspect you are seeking in their late twenties or later. I think you probably don't have a significant other because you haven't sought one before. Now you are at a place in your life when you feel it would be beneficial. So I suspect you will find someone. As you said, you have a good circle of friends. It's like the appliance ads in the newspaper--you never see them till the washer or the frig acts up, then you see them all through the paper!

As for the depression, you have a T. whom you like and a pyschiatrist, so you have the tools to help you with your depression. Unfortunately, sometimes it's "hit or miss" with antidepressants. I am one who needs meds to keep me on an even keel and I suspect I'm a lot like you--highly intelligent and successful, yet troubled by dark times when I'm not medicated right. Please be patient and let your pyschiatrist know of your suicidal feelings so you can tweak your meds.

BTW, I met my "soulmate" when I was in my forties.
