Definitely a scary market. I think it helps to set tangible goals that you can reach. I mean, you can't MAKE someone reply to you. If you define success as hearing back from someone, you'll feel helpless in the instances when you receive no response. And that helpless, churning feeling is what causes most of the terror, I think.
Set certain attainable daily, weekly, and monthly goals. Every day, send out 5 well-crafted letters to places that you've researched. Not form letters, but letters with specific references to the program or firm's recent accomplishments and how your experience (limited though it is) is directly applicable. Letters that discuss why the program or firm is especially admirable, what traits you see in the program/firm, and why you're sending the letter right now. Even when places aren't hiring, they can be swayed by sincere and unique letters. (Has worked for me twice before, in law school and after graduation. And even better success stories for my friends.)
Every week, set up one appointment to talk to SOMEBODY about the legal market. It can be informationals with recruiters or local alumni, it can be a meet and greet with the judiciary or a public agency, it can be a young lawyers' meeting or political social event...anything. Just get out there. Because being around other people is healthy; it prevents you from moping around the house and it keeps you circulating and staying positive. Also, you get new ideas when you're in new situations.
Every month, make a commitment to do some kind of legal work. It can be consulting, free-lance, pro bono, auditing a course, going to an MCLE (even though you may not get credit)...anything. Just do something so that when people ask what you're doing, you can talk about something other than your job search.
Concerning the lack of response, I made a spreadsheet. I tracked when I sent info to people and how long it had been since a response. After the 3 week mark, I sent a letter (different, still positive, still researched) with more info about myself and a polite inquiry as to the status of their search.
