You are a good friend,
I would talk to her in person....
Tell your friend that you care about her....and are worried about her.
Tell her that you realize she is suffering...and you can share what you just said about your pain and your suicidal thoughts. She will probably be relieved to hear you admit this too.
Ask her if she has ever thought about hurting herself.
I thought that maybe the below text might be useful to print out...I don't know.....
Maybe you could go over some of these things with her ahead of time, and then you could even ask her to sign a contract with you that she promises to call you if she is getting into trouble. Others will come along and give you better advice ....hope this doesn't come out wrong.

How can I be prepared for a crisis? Often, crises happen without warning, and the best thing you can do to prepare yourself is to make a crisis-plan list for yourself, a friend, or a family member. This list should be shared with everyone you choose. Briefly describe the kind of help you (or your loved one) would like to receive if you have severe depressive or manic symptoms. Include: Doctor(s)’ name(s) and contact information Contact information of support group and other trusted friends/family members Other health problems and medications Allergies to/intolerance of any medication Insurance or Medicaid information and preferred treatment facilities Things that might trigger an episode, such as life events, travel, physical illness or work stress Warning signs such as talking very fast, paranoia, lack of sleep, slowed down movement, excessive alcohol or drug use Things people can say that are calming and reassuring Things people should do in crisis such as take away car keys and lock up anything dangerous such as weapons and medications Things emergency staff can do, such as explain things, talk slowly, observe personal space, or write things Reasons life is worthwhile and recovery is important How should I talk to a person in crisis? Stay calm. Talk slowly and use reassuring tones. Realize you may have trouble communicating with your loved one. Ask simple questions. Repeat them if necessary, using the same words each time. Don’t take your loved one’s actions or hurtful words personally. Say, “I’m here. I care. I want to help. How can I help you?” Don’t say, “Snap out of it,” “Get over it,” or “Stop acting crazy.” Don’t handle the crisis alone. Call family, friends, neighbors, people from your place of worship or people from a local support group to help you. Don’t threaten to call 911 unless you intend to. When you call 911, police and/or an ambulance are likely to come to your house. This may make your loved one more upset, so use 911 only when you or someone else is in immediate danger.
