I personally give a lot of credence to the practice of writing a letter to Imam al-Mahdi (A) and dropping it in water, as is done by some people on the night of 15 Sha'ban (but can be done on any day): http://www.duas.org/ariza.htm This is because I have seen a lot of quick responses from it.
If it is difficult for someone to write the Arabic, they could print it or even just skip it and just write a respectful personal letter; since it is a non-required act it is not necessary to focus on all the details. However it is good to respect the framework if possible. One can write one's own letter in any language since the Imams understand all languages.
Du'a Mashlool and Ziyarat Ashura are also good things to recite in times of difficulty.
It seems like a lot of people have been going through challenging circumstances recently (even before the coronavirus situation, although that exacerbated things for many people). Sometimes you just have to hold on and push through and have faith that things will eventually get better.
With prayers that things improve for you speedily!
