how did you survive morning sickness

Ok so today I am 11+5 weeks, for about 5 weeks I've had awful nausea and throw up at least once a day, sometimes up to 3 times a day.. I'm struggling to hang in there I am exhausted but cannot sleep and feel like I'm on the verge of puking every second of the day.. I am a first grade teacher and have to be able to function and I've taken a sick day to recoup but it really doesn't help! HELP ME! I have a month and a half until summer and it seems like a lifetime away feeling like this! I have tried: eating before getting up, frequent small meals, tums, ginger, peppermint.. 😩 idk what else to do?
