I think a better way to answer this is: if you don't want or aren't sure you can handle a high degree of independence, then you've got to ask yourself why you're thinking about a PhD in the first place. The whole point of the PhD is to teach you how to become an independent scientist capable of coming up with research ideas, planning out how to execute them, and actually doing the work, all by yourself. No matter what job you land in after a PhD, you're going to be expected to do this kind of stuff on your own. You're going to be running a lab, or managing a research group, and that takes independence. If this doesn't sound attractive to you, if you want to be told what to do on a day-to-day basis, then you have no business getting a PhD. Yes, there are, as someone above mentioned, some people who slide through a PhD with their hands held the whole way, but my general impression is that these people make poor PhD-level scientists even if they have the degree to their name, and usually they end up either failing in jobs they're not qualified for, or stuck with jobs that don't really require the PhD skillset.
Ultimately this is only something you can answer, because it depends on your personal preferences. Nobody else can tell you whether you enjoy being an independent scientist. And yes, the first year or two can be rough, especially if the lab you're in doesn't have much of a support network outside of the PI. This is why I encourage students to actually spend some time talking to people in a lab before they commit to joining it. In the end there's nothing wrong with going for a masters or sticking with a bachelors and getting a bench job, if this is what makes you comfortable. There is plenty of need for those kinds of positions out there. Honestly I think too many people go for PhDs without thinking whether this is really what they want/need, and most labs could use more high quality, intelligent bench scientists and less PhDs. There's definitely a case of too many generals and not enough foot soldiers in science today. From experience I can tell you that capable and motivated bachelors and masters level chemists are more valuable than gold. I wish payscales were better for this level of scientist and I also wish Universities did a better job of selling the value of these positions rather than pushing terminal degrees on everyone... but now I'm coming dangerously close to going off on a rant about the high education system so I'll stop before I work myself into a lather.
