Make the change today. Take the leap of faith now before it is too late, though it might not be for the fainted heart but at least give it a try and try to do it the very best you can for the sake of Allah.
I remembered when I first started to wear hijab & decided to change my lifestyle 360°, my dad sat down with me about four hours during our vacation trip at Bangkok. We had this heavy & heated discussions about Islam , the Quran , laws and Ideology in our hotel room .He even called me an extremist because I took few radical steps such as shaving my head bald (because I used to coloured my hair blond), donated all my sexy dresses and short skirts and bought myself long abayas and hijabs instead of making small baby steps.
However , Alhamdulillah my hijrah ,(transition) from wearing long hijabs (the Malays described as tudung labuh aka Ustazah) to niqab was very easy because he already understood my purpose, faith and persepective. He understood that this makes me happy because I felt closer to Allah and I am willingly doing it not because of any influences, pressure , fanatic ideologies etc.
Change is never easy but you still need to be patient, make duaa always and respect others especially parents and family. Even till today some of my friends didn't understand why I am wearing niqab. Certain things you can explain but some things are better left as it is, & not talk about. Not because taboo or confrontation but it is better to remain silent and say nothing rather than debating and say hurtful things. Off course when we are passionate or serious about what we truly believe , we tend to be very judgemental, strict and see others are not following the word of Allah and everything is haraaaaam and they should repent !!!!
Well my sister in Islam, we tend to forget that we also need to treat our family,friends and especially parents with leniency, poise and respect.
Insha Allah, some day they will understand and Allah will give them hidayah and knowledge like He did to me & the rest of us who decided to change for Allah. Purify your intentions and Insha Allah , Allah shall make it easy for you too.
