The conjunction is within orb (using average orbs of the planets i.e. 9 degrees for Saturn) of both Jupiter and Moon aspects. But left to their own, Jupiter and the Moon especially are not particularly friendly towards Mercury. They will not help it out.
Any inhibition would primarily be due to Saturn conjunct Mercury. Mercury is the natural significator of conversing, playing, joking around with others etc. Also specifically communication for you due to ruling the 3rd. Saturn has a natural effect of creating insecurity in any planets it joins. In this case, a lack of trust in oneself to say the "right" thing at the right time. Even when something happens that shows if you had said that thing it would have been taken very well, and I'm sure you've experienced it, such as someone saying what you were going to say and getting kudos for it - still that inhibition will be there.
Venus is there to help, as you noted. But it also, just like Mercury is starved by Saturn. It's in a better state than Mercury - but it is still problematic and not as readily able to assist. All these will have very detrimental effects on your ability to take care of your "responsibilities" in life, including making the money you need for support (which is likely the main reason it concerns you, or at least one).
There are no planets in your chart really that will naturally give you a "way out." The Sun and Uranus are the only options, but Uranus would be haphazard and cause problems just as quick as it helps you out. The sun isn't particularly concerned either way (except insofar as necessary to have you earn respect and shine - and sometimes being inhibited helps that). Basically, there is no natural state already "awake" in your consciousness that will give you some active out - meaning there is no conventional "action" method you can take to change it.
An absolute change of consciousness is required. That would require simple introspection as to your beliefs that underlie the inhibition, listing however many you find out and then moving them gradually to the point you believe otherwise. The best way I have ever found to achieve that from everything I've looked at and tried is "focus wheels" as defined by Abraham Hicks. I would specifically recommend looking up the "focus blocks" method which is based on that.
Taurus primarily needs assisting. If you're so inclined, some kind of white crystal on your person can help it. As well as lighting white candles regularly with intention towards helping the issue. A talisman for mercury created at an appropriate time to help offset the issues would also help - a cheap example would be a small green clay frog formed when Mercury is in Virgo and rising without any aspects from Saturn or Mars, incensed with styrax with stated intention(of course as of now, that most ideal time will take near another year to form...there are less ideal opportunities that could be taken if inclined for temporary assistance).
It is up to you as to what to do. The most effective will always be a change on a deep level of your consciousness. Followed by an appropriate talisman. The crystal/candles are less effective (though can be made moreso if engraved/lit at appropriate times etc). Some people of course...aren't very comfortable even trying such "nonsense."
