Narrative: This happened after we departed off of Runway XXL in ZZZ on the ZZZZZ5 Departure at the ZZZZZ1 fix. There was weather moving into the area. ATC held us on the ground for about 15+ min for a possible reroute that never happened. We got cleared to taxi to XXL via Taxiway D. I overheard a wind shear warning on tower frequency; so I had the FO (First Officer) enter wind shear numbers into the ACARS. We were cleared for takeoff RNAV ZZZZZ1 XXL. At ZZZZZ1 conditions worsened significantly; we switched to Departure and were issued a climb to 15000 ft and heading of 120. We complied and the altitude and heading bug were set. But I had a bad feeling about this heading. However before I could query ATC; the [airliner] flight that took off before us and flew the route that was intended for us called ATC and said 'Don't turn them to the right! We just encountered severe turbulence and it kicked our ass' ATC immediately turned us left to 270. It was a little too late as we got caught in severe turbulence. We were turned another 40 degrees to the left. The aircraft was very difficult to control; I told ATC we are unable 15000 ft and was issued 5000 ft; I further asked for 4000 ft as 5000 ft would have put us right in the cloud base and even more turbulence. The FO handled the situation exceptionally well keeping control the best way he could. It was a struggle to maintain altitude; heading; and airspeed. The altitude loss and gain was +/- 200 ft to 300 ft; airspeed loss and gain was +/- 30+ knots and heading deviations of 10-15 degrees right and left of course. I called out the deviations to the FO and advised ATC of our progress. The goal was to simply escape the severe turbulence. We exited the turbulence got back on airspeed; altitude and heading and maintained all further instructions. My first priority was to check on the Flight Attendant and asked if everyone was ok and not injured; she responded with 'everyone is ok'. We continued on to ZZZ1 without any more incidents.I'm not sure that there are any suggestions on this as it was weather related and happened very suddenly and unexpectedly without a way to predict the turbulence event. ATC did a great job of vectoring; we did a great job in getting out of the turbulence and maintaining control; and the flight crew of the southwest flight did a wonderful job of quickly telling ATC to not turn us to the right. I feel an [Report] is warranted because we couldn't hold altitude airspeed and heading due to the intensity of the turbulence.


Second narrative: We were departing from the ZZZ airport on the ZZZZZ5 departure. We were in the turn going towards ZZZZZ1 and there were thunderstorms just north of the airport. Once we were in the turn towards ZZZZZ1; that was when the severe turbulence started. ATC had issued a turn to the right about 100-120 heading; but [the airliner] suggested a left turn towards a roughly 210 heading. I'm not entirely sure when we were out of the turbulence but once we were clear from under the clouds; all severe turbulence stopped. I had decided to not climb up to the issued 15000 and stopped climbing to remain clear of IMC conditions. We maintained 4000 ft until clear from under the clouds as well. We experienced about plus or minus 30 kts up to 280 kts. We also experienced altitude deviations of plus or minus 500 ft. I would suggest to abandon any STAR in the face of severe turbulence. I had my reservations about turning head first into the storm. We should have turned to the south and not to the north to avoid anything to do with the storm.
