Happy World Hijab day!
There's two things to keep in mind:
1) Your choice to wear hijab should come from you and your desire to please Allah. As a hijabi, especially in today's society, you're going to doubt your decision, but if you have a sincere love for hijab in your heart, it's going to make your difficulties a lot easier.
2) You have to remember that nobody is perfect. A lot of people think i'm going to perfect this aspect of my deen or this aspect before I start my hijab, but the reality is that as hijabis, we're trying to perfect our deen as well, so you shouldn't let that stop you from making that change.
In the end, just put your trust in Allah and Allah will help you with anything you're going through.
