Engine stalling and will not start after momentary high RPM drive

I was driving my car entering a highway so I was speeding up. I didn't realize my car was in manual mode and only in second gear (music was up and just didn't notice), my car got up to about 45 mph before I noticed the high rpm's. I let go of the throttle and moved the shifter back to the right, to automatic. But right after I did that the rpm completely dropped and the engine stopped. The engine temperature gauge was still less than half as the entire time of driving in second gear was less than 1 full minute. But when I opened the hood the turbo was glowing red hot. It only started again after 10 minutes. I drove it back to my place which was 45 minutes away (not on highway speeds), but it shut off before I reached home. The car started afterwards but would just drop rpm instantly and shut off, then afterwards it wouldn't start at all. (Didn't continuously try didn't want to cause further damage). Money is kind of tight right now so I was wondering if anyone may have any ideas as to what might have happened before I take it to the mechanic. Any help would be greatly appreciated.
