23 yo father of 6mo baby, about to quit medschool, from Brazil. In need of any guidance to help me get any kind of job online.

First of all, I am sorry for the title, I recognize it may be offensively dramatic for some people who are also facing dificulties in life. That said, I am starting to freak out as I notice all the responsibilities a growing baby imposes. Not that I didn't know about it earlier, and this was not an undesired pregnancy. My wife would take care of her until I had my diploma to start working as a doctor, two years from now. The thing is: Her mother (my mother-in-law passed away on october and since then, she's deeply deppressed. She takes three different antideppressors and one antipsychotic because of hallucinations. Fortunately, things are slowly getting better, but not so much as to make her able to take care of a baby by herself most of the day. And for the first few months of life of our daughter, I received lots of help from family members and asked for a 6 month break in my University, where I study Medicine. Soon after she started showing the first signs of deppression, I started to look for some job online to make sure we would be financially safe. I discovered Clickworker, Leapforce, Appen, Lionbridge, ISS and applied to all of them. FAILED Yukon, which was the worst thing that could have happened, since the pay os great. Lionbridge, Appen and ISS never returned my e-mails after the initial application procedure. LUCKILY, I passes Clickworker and UHRS. Saddly, though, is that the HitApps for Brazilians are scarce and have low payments. Even then, I managed to make about 200$ a month, which, due to the exchange rate, gets close to R$ 1000,00 (above minimum wage for Brazil). But these recurring issues and the fact that I have to start Uni again in two weeks, are making me freak out with concerns for both my wife's and daughter's safety. Therefore, I need to get any part-time online job that has a stable pay. I don't mind if it pays a few hundred bucks a month only, as long as it pays consistently.

I ask for your advices considering that I don't have much skills but I am willing to out every effort in learning something that Will get me a job. I speak english, portuguese, spanish, italian, german and french. (the last two of these are restricted to writing/listening/reading). And have many interests in varied topics.
