First, congratulations, you have accomplished a lot by getting a CS degree and should feel very proud of that. Now before presuming you can't handle a workload at a company that isn't all testing-mensa-crazy, you might want to look into how you respond to this stress before evaluating the best course of action. As other commenters have said, there are many options, but at the root of it you should understand what/why you feel this stress and it would be best to get professional advice on that. I'm the last person who wants to advocate pharma-everywhere solutions, but I've worked with some extremely talented people who otherwise struggled through life and managed to find the right formula that worked for them.
