In a country where you earn $3 per day, you should focus on making money online.
Good news for you, the threshold of living off the online money is way lower in your country than in most other countries. With $300 per month (which is absolutely nothing in Tier 1 countries) you can probably have a decent living standard in your city.
Your income heavily depends on your skills and also the difficulty of your job. You can make $300 per month easily just by creating high-quality websites / eCommerce stores, optimizing them for SEO, and selling them. But for this, they must be high quality, and to make high-quality stuff, you need the required skills.
So instead of pitying yourself, you should spend your remaining 16 hours per day to increase your skills in whatever field you want to operate.
