Does medication do more harm than good? What's the point of taking them?

Sure there are some benefits but for my case I think the negatives outweigh the positives. Without my medication I feel more even. On meds, I feel great but as soon as it wears off I feel like crap. The highs and lows are just too much and I do not want to be dependant on them for the rest of my life. I rather feel slightly miserable than have the soaring highs and crashing lows. It's just too much for me. I think most forms of medication are a scam and a bandaid solution to a deeper problem.
