Okay to regret decision?

[Fallen]

So I decided 2 weeks ago on the program I was going to accept. I declined an offer to a very good professional program in favour of a PhD in Comp. Biology. For some reason, at the time, and the following 2 weeks, I was delighted with my decision. Right now, I regret it. I feel like I don't have enough experience, and I'm not quite sure if I will be able to succeed. I have the skills in their raw form - I know my biology, statistics and programming - but I don't have any experience putting all of it together (and I made this clear in my application) in a research setting. 

 

Is it normal to feel this way?

I should add - prior to starting in September, the program will be placing me in a lab as a summer student working on a computational problem, and assigning me readings to help get me up to speed.

It's normal to have doubts, but they excepted you knowing your current level. Everyone program is different, but we were told in our interviews not to worry that we weren't good researchers yet, that is the point of a PhD program, to train you to be a good researcher.

Yeah, that sounds pretty normal. If you're choosing among several options, whatever you do, you are giving up on these other possible futures. You're never going to know what might have been; but that's true regardless of your choice. It's ok to worry, but try to remember what led you to choose this path. The program that accepted you had its reasons for doing so, and it'll be able to support you and train you. I'm sure it'll work out just fine.
