What do I mean by that? What I mean is that you should take it one day at a time, or even one outing at a time. Sometimes the future seems to stretch on forever and ever and you don't think you can make it that long. You want to give up before you even begin.

So sometimes the best thing to do is to keep you mind focused on what is immediately at hand. Allah SWT will take care of the future. If you have to go out to the market, then concentrate on being able to wear hijab just for this activity and on getting through it. If you do get through it and nothing bad happened, then give thanks to Allah SWT for making it easy for you, and turn your mind to your next outing.

Or if you have to go out to school or work, then concentrate on being able to wear hijab just for this one day and on getting through it. And give thanks to Allah SWT when you have made it, and turn your mind to the next day.

Eventually the outings will turn into days and the days into weeks, and the weeks into months. One day you will realize that you have been wearing hijab for quite a long time and it isn't really as bad as you feared, and Allah SWT helped you get through it. Don't be ashamed. Sometimes it is like this. The most important thing is to have sabr and keep your trust in Allah SWT always.
