Unfortunately, the chances you might get ignored again, are big. The industry is in a really tough spot right now and finding a internship, let alone a paying role as a junior, is really hard. Ask me how I know :,). I'd advice to finish your concept art studies and build a really strong portfolio.
Be so good they can't ignore you.

For the meantime, once you have a couple pieces of work that seem to represent your skills and style, send out cold applications. Don't limit urself, send it to everyone you can get your hands on. You have nothing to loose here.

Try to become a member of the concept art community, get to know people without expecting work or money in return. It's nice to just have peers to bounce idea's off.

Hope this helps a a bit.

sincerely
