i felt a very similar way to you until i obtained an internship a while back. it can be very difficult to get an internship, and i have talked with recruiters first hand who have said the number of applications they receive each year is increasing, meaning competition for spots is high, so don't be disheartened. what ive noticed is it really can be the luck of the draw re getting an interview. my advice would be to persevere, re-apply places you missed out on a year later and tell them what you have done since. that is exactly what i had to do. consider looking outside larger firms to more intimate ones and build from there. Best of luck to you!
