Is a Trazadone overdose lethal?

I have about 3000mg sitting in my bathroom right now... They are just sitting there waiting for me to take them. The problem is, I don't want to die I just want to escape for a little while... I need a break and I can't handle the **** that's piling up day after day. I hate the thought of quitting but I'm so tired... I want to take enough to really let me be free for a bit but not pose too high a threat of death. Please help.
