I'm sorry you're still struggling. These infections take years to recover from which makes schooling difficult as you know. I would think about
discussing the status of your scholarship and if you could postpone it while getting well because even if you try antibiotics, you will likely have symptoms for some time to come. You may recover faster since hopefully you've had some benefit from the natural methods you've used so far.
To answer your question - yes, DS is much better after pulsing antibiotics (J Clinic in WDC) and anti-malerials/some supplements/herbs plus herbal treatments we continued after running them by the clinic. He was 13 when diagnosed and we let him have a say in his treatment. He was untreated for at least a year. It took 1.5 years before he was 95% better and those years were tough with all sorts of symptoms coming forward from the infections and from chronic fatigue.
Working out, lifting weights, sweating regularly, magnesium, vitamin D/lots of sunlight, medical mj (had it been legal and he was older), probably taking more Motrin and Benedryl, may have helped him miss less school - definitely the medical MJ - which I'm telling you since you're in college and may be in a legal state and could try. He only tried it once but it was like a miracle and let him get out of bed and go to school that day.
Everybody is different so it's hard to say which path will work but if your heart is telling you to try something additional, you should probably listen. However, staying in school may be a challenge. I'm so sorry for your struggle at this time in your young adult life and with what I'm sure feels like a huge responsibility!
