It's a horrible experience either being laid off, or leaving a job under a cloud whether of your own making, or just some rotten circumstances.
It's perfectly reasonable to be a bit anxious about how you'll manage the inevitable questions at your next interview. Basically your approach will cover these 4 important points:
1. Be as honest and direct as possible.
2. Keep your explanation brief.
3. Move on to the next question after having finished your answer on a positive note.
4. Lastly, take responsibility and don't blame others. You could mention what positive things you've learnt from the experience.
