If you’re taking Cymbalta for depression, the first thing you should know is that depression usually has a negative effect on sex drive. Some anti-depressants also reduce sex drive – and cause weight gain. Definitely see your doctor; a change in anti-depressants could immeasurably improve your situation.
I second all those who recommend exercise: Not only will it help you vent your (considerable) stress and get your weight under control, but it will also raise the serotonin level in your brain – which is one way to mitigate depression. Exercise has been shown to be helpful in reducing depression.
Anti-depressants are nice, but they’re much nicer when accompanied by therapy. Any one of the things with which you’re coping – depression, weight gain, loss of sex drive, transition to a new job (and a high-stress one at that), changes in your relationship with your partner – could have underlying causes which would benefit from some airing-out and insight. Moreover, all of the things with which you’re coping are inter-related and, in truth, it will be hard to untangle them and resolve them until you get at their root causes.
Anti-depressants and exercise can help you eliminate negative symptoms (depression, loss of sex drive); therapy helps you get at the underlying causes of those symptoms so that you can move past them and find better alternatives for yourself. Talk to someone who can help you unravel your situation and, taking one thing at a time, get yourself to a happier place…where you deserve to be!
