Pardon me if I'm wrong, but I'm getting the impression from your posts that when you say you accept Jesus, you really don't know what it is you're saying. Like you heard a bunch of other people say it, and you said it to, and it didn't do anything for you.
In other words, I'm getting the impression you may be ignoring God, not the other way around. There's a lot more to it than just saying that you accept Jesus, and if you're still having thoughts of killing yourself, I have to think that you're not really living the lifestyle you should be.
And that's how you accept Jesus: learn what he taught, understand why things happen to you, and try to live the life he led. Bad things will happen to everyone. Maybe all the troubles in your life have been put there to coax you back to God and form a deep relationship with him? Since you're on this board, and if that's the reason, it's working (so far).
You shouldn't kill yourself because God does love you, and because we've all got some kind of purpose in life, and it sounds like you haven't found yours yet. My suggestion would be, consider how miserable, challenging, maybe depression, etc... your life has been. Now think of all the people who are worse off than you; maybe the homeless, orphans, people in undeveloped countries. Realize that everyone suffers and thank God every day that he's blessed you to where you don't have to suffer as much as others. Finally, go out to those people who are suffering more than you and help them. Whether it's helping at a shelter, missionary work, visiting shut-ins, doing medical/scientific research, or whatever. Clearly you don't like the suffering in your life (no one does), but if you're having no success in taking it out of yours, do your best to take it out of others.
Just saying that you accept Jesus doesn't cut it. Live the life. Do good deeds. And don't get too frustrated if things still are a little crummy. Remember that God does still love you, and he wouldn't give you something you couldn't handle. If you learn and live a Christian life, it won't guarentee a life free of suffering, but it will help you to understand and cope with your sufferings, and it'll show you why you shouldn't kill yourself.
Hope that helps.
