my meditation practice question

Would like to ask if my method of meditation(Mahasi method rising-falling) is correct. When some feeling arise in me, most of the time, i can noting the feeling was somewhere in the body( example: scare feeling near my abdomen/ back of my body). When i concentrate on that feeling, i will either yawn/ tears coming out or even deep sign. Then i will feel better after every 'reaction'. I would like to know when i noting the feeling part inside/outside the body, is this the right way? i did not do it purposely but i can just feel it when i concentrate' Looking for a meditation teacher for years(answer my question from time to time- prefer online). Been practicing meditation for years on and off as i could not really get a teacher. I practice and learning teacher S.N.Goenka method before but i feel Mahasi method suit me. Unfortunately cannot get one to help. Appreciate if anyone out there know any online tutor/ bante who can online help in meditation. Thanks
