I am a finishing PhD student in the field of cognitive neuroscience. During my PhD program I was underperforming than anyone else in my department (in my belief at least). Although I liked research, or at least some aspects of it, I had become so emotionally exhausted in the absence of support in many respects, and recently just wanted to leave academia as soon as I finish the degree. So, when I had started applying for postdoctoral positions in the last winter, thinking that I should at least give it a shot, I never ever expected that any reasonably-minded PI would show an interest in hiring me after looking at my CV. But surprisingly, several PIs wanted to interview me and I even got a few offers. (BTW I hope this can encourage some people who are depressed and discouraged just like I have been. I was in terrible shape in past years and needed medication at some point). 

So, right now, I am considering the job offers thinking whether I really want to take up this opportunity. At the back of my mind I want to become successful again as an academic researcher although I am still feeling tired. I guess I like research in general, but I also have a serious math/stat anxiety, which is terrible. I did not have a solid training on math or stat in college (wasn't a STEM major) nor did I have experience as an RA or so like other people. I know that these are all lame excuses after all the years in the doctoral program. I am a very slow learner when it comes to quantitative aspects, and my advisor was not being really helpful in many aspects. 

I think my strength as a researcher is that I can generate interesting and creative ideas. According to my advisor my works are creative. Also, I like to read others' papers and think about them in my head. I also like to write. Those things come naturally to me, although other people might also feel that way, and having a great skill set in coding and analyzing might be a lot more precious these days. Anyways, with all the job offers that I have to decide soon, I find myself worrying about whether I would be able to quickly pick things up in the new place, which is not a good sign. I will do my absolute best to strengthen my math and programming skills if I decide to give it another shot, but I am not sure if these things can be overcome. Also at this point, I might as well be happy outside academia. 

I would like to hear what other people think about this situation. Thank you!

I am adding this after reading some comments below. Sorry if this was not general enough and considered off-topic. I am new to this StackExchange site and still figuring how to use it. My question, at a more general level, would be **whether postdoctoral training can improve one's poor quantitative skills**, especially given the fast pace of research that is required of a postdoc. 
Thank you for all the great comments so far.
