I’m finished

I genuinely don’t know what to do. I just turned 18 and wanting to try gambling and now I don’t know how to stop. Every time I win I lose it all the next bet and idk how to stop. My dad gave me $200 as a loan bc he didn’t know I would use it for gambling. Thats the reason why I was gambling in the first place because I need to make the 200 back before end of summer. I would get a side job or smth but my family is going in a different country for vacation so I won’t be able to work. I am not sure what to do. I desperately need the money or else if I don’t get it before summer I might end it all cus I can’t do this shit anymore. Is there any advice on how to stop gambling? Also, how do I earn $200 online fast?

Please help me idk what to do I’m genuinely freaking out
