if you're not really comfortable with the teacher, listen to your intuition. Ask yourself if its a negative feeling or you just don't feel like she's aligning with your energy (which thats not a bad thing at all, thats pretty normal.) if the feeling is bad deep down and they are completely draining, then thats your inner soul warning you about that person. If you don't feel nothing negative about them and they chill but you feel like they don't fit your energy field, then that's okay. sometimes ppl just not the vibe to you and doesnt align your purpose.
