Possible solution

Create a holiday that promotes mental health research.

Come up with a holiday that will be celebrated every year that promotes mental health. Find an appropriate medium such as YouTube and ask the most renown youtubers to promote this holiday on their YouTube channels. Also, create something like a shirt to advertise for this holiday and have all of the revenue donated to institutions that need the funding in order to have the appropriate technology that enables them to find the casuations for mental health rather than probably correlations. Also reach out to companies that would be willing  to help promote the t-shirt (or any product created for the holiday), which will allow companies to show that they as a company are not only about profit margins and that they as a corporate due indeed care about the welfare of the public. youtubers as well as large corporations need the publicity and mental health research needs the money.

The funding for mental health research as well as the advertising for mental health research to a large audience.

There is no definitive answer for this because research only shows that there are correlations betweenness variables that may be the cause for mental disabilities. The solution to the answer would need to address the main causation for mental disabilities, which have not been solved and could potentially never be solved for. Thus, my proposal is to address an assumption in the logical, which is if we can find an adequate way to advertise a "fun holiday" on a medium that reaches most of the world then we could potentially start a movement for mental health. 

hopefully it helps the audience that is unaware of the significance of mental health and it will help the audience that suffers from mental health who seemed to have been neglected from societial focus. 

By the amount of views that each youtubers gets on the video. - If YouTube subscribers that promote it on their YouTube channels will enable their audience who are their subscribers to be influenced by these individuals which will be millions.

It is unique in the way that it asks for less funding than most solutions will and it depends on the ability for society to help one another to achieve a goal.

It reaches these regions because it connects everyone who is connected to the internet. Then this should enable a shock effect in society to help more individuals in need and to help the uninformed audience about the significance of mental health.

they will access it if it's on YouTube or in stores. Also, if it is popular enough then we would create a website for donations and then advertisements throughout other websites such as Amazon.

It should be relatively easy to finance as long as we have a reliable distributor and as long as youtubers and companies are willing to participate for a great cause.

the limiting factors come back to youtubers and companies willingness to help. 

The reason why I am applying is because I saw a last minute email and if there was anyway I could possibly help a group of individuals trying to do society some good, then that's all the satisfaction I need.

no one, I'm just a college student studying for law school who wants to help if I can. It's just a solution that is inexpensive and only requires everyone's willingness to help.

No one.
