Are you sure you’re underperforming, or is that just an idea you came up with yourself? Have you talked to a boss or manager about their expectations for your role and if you are meeting those expectations?
It may just be a self-sabotaging thought, and getting confirmation that you are meeting expectations could let you relax and work at a preferred or natural pace without stressing about your performance.
Not surprising; it’s far more practical to get information across by switching to a language you both speak fluently. If you ask the other person to help you practice the language, it would change the task from “information” to “training”, and you’d probably have better luck in speaking German if that’s the expressed goal.
Communicate your wants, or you’ll end up with the most efficient route to the end of the interaction. 'Tis the German way.
That sounds horrible. I struggle with energy a lot, but not to the degree you’re describing so I can’t imagine…
I generally think we should be careful with self-medicating, and I don’t know if this is allowed on this forum so I’ll accept any consequences:
Have you tried amphetamines/stimulants? Like a very low dose, not anything to make life a party but just a hint to get yourself going, lower than anything you think of. Only early in the morning and no refills during the day, so it won’t interfere with your sleep and won’t build tolerance. And only pure shit, a thoroughly tested substance, not street-meth or other untested garbage that can be mixed with fentanyl and cocaine and a host of other substances - I mean like actual adhd-medication.
It’s not going to solve whatever underlying issue you have (unless it’s ADHD, lol), but if it makes you function and feel better it while figuring it out it could be worth it. Ideally as prescribed by a doctor to monitor your heart and health over time.
Regardless , I hope you find whatever you need to feel better and more energetic.
We can’t fix other peoples issues for them.
We can choose to support them if they are actively trying to fix their own issues.
We can also decide that even though they are trying the impact is too big on us and distance ourselves.
But if they aren’t actually trying to better themselves there is nothing we can do except protect ourselves.
Your sister needs to look into co-dependence and trauma-bonding (if not in this case then for future reference), and focus on becoming emotionally independent rather than confusing nurturing with doormat. She can only fix her own issues, not her friends. And learn that not every friend is worth the title.
