"I'm freakin 19 and I can't get my life straight. What a waste of a brain."
You make it sound like others have their lives sorted at 19.
What about those who are 55 and haven't got a clue?
Hint: the majority of people.
As for a waste of a brain, there's only so far external factors can influence that. Your brain will only waste if you let it.
What are you doing with your free time? Posting on BBS boards and complaining about life.
You could be learning programming or languages (I recommend C# for programming and Japanese for languages) or educating yourself on matters social, political and anthropological.
Suggested reading:
- Alexander Berkman
- Albert Camus
- Franz Kafka
- Friedrich Nietzsche
You could also turn your time to other, more worldly pursuits: Is there any way you can offer support or help to your family or wider community?
The main problem is that there are too many things to do and it can seem overwhelming, but you are the only person who can make what you want out of life.
If you need energy, drink energy drinks or coffee until you feel like you have to do something or your heart will explode.
(tip: a lack of motivational energy will help when reading some of the aforementioned authors' works. You'll be able to identify with a lot of the thought processes behind their writing.)
Good luck.
