Help me save my falling bussiness.

Hello I'm Arvin,20 I'm a college dropout, its not because I make problems or picking fights but I'm not from a rich family background and my brother is soon gonna enter college too and he will needs much money too. But the main reason is I always wanted to be a businessman/traders and ive decided that will my my job so I decided to drop out from college to chase my dream. But like you guys know starting a business isn't easy and it needs money, nobody in my family supporting me so practically I'm walking on a lonely path. I'm starting with $40 to buy goods from china and now that money becomes $1000 but as you know importing goods have rules and its own problems so sometimes my goods can take up to 3-4 months to arrive to my house and a small businessman like me its a hard thing because I wont make money in 3-4 month when I'm out of stocks. I don't have a shop I sell my goods online. When my goods haven't arrived I started another things like trading stocks, mining cryptocurrency. Its tough as a college dropout and without anyone supporting what I'm doing, Please don't let my dream died and I hope you guys can give me a little of your money for me :). If my business failed I must go out from my house, work with my high school diploma and I need to abandon my dream, so any help from you guys to improve my business is appreciated! Thank you!

I'm mainly interested in computer and car accessories(headlamps,LED,HID) you can see some of my goods that I have sold.
