TheLefty,
I'm not entirely sure of your situation as you've only shared a little. I assume you are a high school senior.
THe first thing I would do is reach out (phone & email) to all the coaches you've previously contacted. Do this during the week not weekend when they are less busy. Share your spring & summer schedule, and desire to learn more about their programs. If they are close by, go see some games to see how they do things. Tell the coaches you will stop by to see some games, and do it. From this point forward, you need to follow up on everything you say and do.
At the same time, you need to take a long hard look at what you did this Fall that wads successful and unsuccessful. Be honest with yourself......Are you looking at the right schools? Are you looking at the right talent level? What other schools may be interested that fit your profile? Make a list of 20-25 schools, and go after them. Figure out how to get in front them whether it showcases, camps, or whatever.
Freaking out isn't going to help your situation. Get your travel coach involved or high school coach to listen to your thoughts about college baseball. Maybe they can help.
Good luck, and please keep us updated!
