It's inevitable to face losses in trading even you're knowledgeable or a skillful trader. Because not all the time, everything you've planned for will going to happen. Thus, it's a must to be prepared in this kind of situation to not be discourage or disappointed that can affect you to just quit.
Well, we're the ones who can tell if it's already time to stop or continue being a trader. If you think it's not healthy anymore mentally (for overthinking) and financially, then don't be hard on yourself. Trading might be profitable but it's not for everyone since not all are able to profit. Therefore, try to improve to minimize the chances of having losses. If it's not working, trading might not suited for you, just like some traders who quit and look for other opportunity.
