I'm currently a PhD student in biological sciences and I'm hating my current situation. I'm in my last year, but the pressure is immense. I wanted to do a PhD because I wanted to work with research, but I think I have finally realised that that is not going to make me happy. I don't cope well with the constant trouble shooting (why can't anything work just from the first try?), endless deadlines (focus on the data analysis, but do lab work at the same time, prepare for this presentation, do this, do that, random risk assessment here, write this manuscript) and I hate how I'm responsible for how my experiments goes (you can't control biology!). I also don't appreciate how coming in at 9 and leaving at 5 isn't even the bare minimum: You're expected to work evenings and weekends. I do also feel slightly bullied by my supervisors (they don't listen to me, they make faces at me, they treat other students differently), but even when I try to imagine what I'd feel like with better supervisors I still don't think I'd be happy.
It's gotten so bad that it's actually affecting my health. I often sleep badly, I have nightmares related to my research work and uni and people here, I get headaches, my stomach gets upset and my blood cortisol level is literally elevated just because I'm so stressed all the time. I'm also starting to feel like I might be downright depressed. Everything just kinda feels hopeless, and I don't really give a **** about many things anymore. I feel bitter and tired. Cliché maybe, but I don't feel like myself anymore.
Even if I can fight my way through this last year, I'm not sure it's worth it. I'd do a post doc after, and that's pretty much the same as a PhD student, but paid a bit more and more responsibilities. The above issues would still be there. You also get zero job security as a post doc. Very rarely do you get tenure when you work with research. I don't think I'd like one of those prestigious industry jobs where you need a PhD either.
I feel like I just want a simpler life. A stable, moderately difficult (instead of soul crushing and health destroyingly difficult), fairly OK paid job. I want a job where I can work til 5 and feel "OK, some things remain to be done but it's OK." instead of "I can't keep up, I'm drowning in things to do". So I'm thinking of quitting my PhD, because right now it feels more like I'm only continuing for my supervisor's sake, rather than my own sake, because I feel like I should, like it's the just thing to do.
The two career options I'm considering is either police constable or (more likely) biology teacher for A level students and adult school leavers. Both seem to pay better (once fully qualified) than the pay for a post doc. Both seem less stressful (yes, even working as a police constable seems less stressful than working in academia). I can train to do either and get paid whilst doing so (apprenticeships, bursaries etc).
Any advice on any of the above? I feel like such a failure.
