3-year old tantrums with mom

Dear mothers! Any advice from experience: My daughter has many tantrums but only with me (or when I am present). Almost never with father, never with grandparents or at school. Usually when she is tired but not all the time. True that I am less strict than my husband but I try to be. Very difficult to stay calm myself as I am a very nervous person already. Tons of advice on internet which is not always easy to implement.
Thanks a lot!!!
