For me in the past when I have found myself in this iffy spot, I ask myself "Can I promise myself that I am safe right now?" If the answer was no, I would go to the emergency room. If you are just having thoughts I encourage you to talk to someone close to you about how you're feeling, and ask them to be with you during this difficult time if you feel that will help. If it will also help, give someone you trust your medication and have them give you your proper doses when needed. Even just having suicidal thoughts is difficult and I hope you feel better soon.
