What do I do from here?

I'm 17 and my life has been chaotic to say the least. I'm dealing with some pretty bad depression for which I'm taking medicine for, my little sister is a diabetic and hasn't been in the best of health lately, and my mom has really bad health and I don't know how much longer her body can take it. Also, my parents don't get along at all and last night I heard my dad talking on the phone to another woman. Then I heard him whispering about meeting her, I'm assuming it was a her, in 15 minutes. Then he comes in my room thinking I didn't hear the conversation and tells me he's running to work and then going to get something to eat. I am devastated. I had an idea that he was cheating, but now that I have proof...I can't take it. And it's not just a suspicion. I know how my dad is and I know that wasn't a man he was talking to last night...it wasn't just "one of the guys". My depression goes up and down, and lately I've been suicidal a lot. I feel as if there's no hope left. What do I do now?

I'm sorry you are having a difficult time right now. But just remember there are people that have it a lot worse right now. And when things seem like they are at its worst the only they can only get better from there on out. Do a lot of praying. Know that God would never put you in a situation that you can't handle and grow from. Your Dad seems to be going through some issues his self. And I think if you let him know that you know about this and it hurts you, it will open his eyes and show him how he is potentially breaking up this family. Whatever you do, do think about suicide. That is not the answer. You have a lot of life to live and things aren't always going to go your way. But you have to fight through the hard times to enjoy the good times. You are still very young, don't beat yourself up for things that are out of your control. Seek some counseling or guidance from an elder. I will tell you now that at your age I thought life sucked and it was never going to get better. But needless to say I have grown up and see the good in life even when things are hard. I just lost my baby 2months ago and I have never hurt so much in my life. But I know that I can't let it keep me from living life. I am so sad everyday and I long for my baby boy but he is in God's arms now looking down on me. We are all God's children and he has plans for us all. Just be strong and know that things WILL get better for you. I hope they do!!

when my life went to **** in 1972(my father died and my best friend died 2 weeks later in a car accident) I joined the US Marines and Boot Camp at Parris Island set me straight, got my head out of my worries, gave me a new purpose in life. I got out of the Marines in 75 and in 76 joined the US Army, I retired in 1994 with nearly 22 years of service and I remember joining the Marines in 72 was the best thing I could have done. Just a suggestion.

you should diffently see a doctor.. suicide wont solve anything
