Say no beacause you love and honor yourself. It doesn’t matter if everyone around you wants you to do it, if it feels off to you – say no thank you.
You don’t have to explain, justify or try to make it up to them just because you want them to be pleased – what about you??? If you do this thing they want you to do, you go against yourself! You have a guidance (your emotions) for a reason, start loving and honoring yourself by listening to your inner guidance.
