Groceries for next weeks

Hi my name is David (Shuresh) im 20yo from germany and from an lower class family. I finished school during lockdown and cant find a job due to lockdown and to be dead honest I was lazy and unmotivated in the past years. Lockdown is getting extended every month currently . My bank account is slightly in debt for a while now and I still gotta pay for stuff like my gym membership every month even tho its closed. I need money to buy groceries for the next weeks which is my main goal but if I somehow raise way more I will most likely start investing or atleast keep it. Ive tried several sites so far but it wasnt helpful yet and my bank is currently at -37€ and im not allowed to reach -50€ or I get fees which will be the case start of next month so if I can atleast get about 20€ I will evade reaching that cap and dodge the fees for some days more atleast. Thanks for reading I appreciate it and have a great day
