Hello, six months ago i started working for my university's formula SAE team, it was very hard work (especially since it is unpaid), sometimes we would start at 8 am and end the day at 10pm, but the excitement about working on a race car made it worth the hassle. I also liked getting to know a lot of new people and I was rewarded for my hard work by being able to go to all the races of the season (with paid hotels and trip). This is where the good part ends, Unfortunately, i am addicted to benzos for sleeping and social anxiety, and didn't have the chance to restock before departing for the first race, so from the second day onward i was on full on withdrawal. Needless to say i didn't rally sleep more than a hour per night, was a paranoid, anxious moron during the day and overall pretty much useless. I still tried my best but in that state i couldn't really do anything. After a while i became the end of every joke, even during the celebrations (we ended up 3rd overall), and started to feel like i don't belong in that group. Those seriously were the worst 5 days in my life and now i'm thinking of abandoning ship. I hate being seen in such a sorry state but I would hate even more being unable to fix this whole situation, but i seriously don't have any strength to go to the next race (1st of august) or work on the car. What irks me the most is that if i give up now, i'm just throwing away six months of my life, six months of sacrifices for nothing...
Sorry for the rant, should I try fixing this mess or just stop giving a fuck and bail?
