I do know what you mean about the fear of appearing 'weak'. I'm going to share something that deeply impacted my life. I hope it helps. This is a bit of a life story, so please bear with me...
After five years of being unemployed and not being able to find work, I decided to move to a completely different city where the job market was booming. I had two young children with me, one who is severely medically challenged. After the move, I was able to obtain employment rather quickly with a growing Residential Property Management company. I was quickly thrown into the responsibilties of Work, Home & Family - something I was not accustomed to and had a really difficult time balancing everything. Work was very demanding of both time & energy, I had growing issues with my disabled son, and my house was getting messier and messier. I couldn't keep up, but I smiled and pretended everything was fine. Everything was NOT fine when the Authorities raided my home and took my children away. I was severely depressed, I was severely sick and I was nearly dead - all because I pretended everything was okay.
I know it's hard right now to entertain the possibility of discussing things with a therapist, but I really would like you to not let things become as badly as I did because of fear.
As for the anti-depressants, if you feel they're not working, discuss it with your doctor again. He may ask you try a little bit longer or he may need to explore a different drug for you.
