I have insomnia and it seems I've developed tolerance to trazodone. I won't see my doctor for 3 weeks. What do I do? I haven't slept for 2-3 days. I suffer from insomnia. I feel like crying all the time and I'm depressed. I am 18 and I'm starting college at the end of July. Is insomnia going to affect my life? What should I do?
