Female low sex drive, I take diazepam and venlafaxine?

Hi, lynn!
Your venlafaxine might be the culprit and low libido is also typical in depression. You really need to discuss this with your doctor for professional advice.
If you want to stay on an antidepressant you might ask about bupropion (Wellbutrin) which may be less apt to cause this side effect. There has also been some improvement for some users with male enhancement medications like sildenafil (Viagra).
Two other medications that might be prescribed for this side effect are flibanserin (Addyi) and Bremelanotide (Vyleesi).
Best regards and good luck with this!

Both Venlaxafine and Diazepam will take away your libido. You won't get it back by popping another pill.
