Sinead O' Connor began a campaign on Twitter last month in which she claimed she was looking for love. However, recent tweets on the issue of suicide from the Irish star have been a cause for concern.

The 'Nothing Compares 2 U' singer said that if there was a way to kill herself without her children knowing it was self-inflicted, she would:

"Psychiatrist says I'm a bad mum and mental for talking so openly about sex in public...I wish suicide wud kill me. I want to go to heaven so bad. Have for yrs...But I don't wanna abandon my kids. If I cud die without them knowing I did it myself I wud."

The 44-year-old mother of four has since taken to her blog in which she explained what she meant. In a lengthy post, she says that she is not promoting suicide:

"I do believe suicide is a sin. Because u may as well have murdered every one who loves u even remotely. Including 'God'. And we all have people who adore us.. Even if we think we don't. Its a lie too, suicide. It doesn't solve your problems. It only makes them infinately, un-countably worse. Its a permanent solution to a temporary problem. Which brings u a whole rake of new karmic problems. Its selfish. And s**t. So.. Let's not do it."

She continued to explain that she is normal for feeling this way:

"BUT Its ok to FEEL suicidal. That is most definately neither a sin nor a sign necessarily, of madness. Its quite normal to feel that way sometimes.And its not only ok but MANDATORY u SAY when u feel suicidal and ask for help.. And anyone who criticises u can f**k off so they can for themselves and is only afraid of their own 'madness.' "

The singer, who was once ordained as a Catholic priest, wrote in the Irish Independent on September 18 that she has been using her Twitter as a way to get over her depression:

"I woke up one day about a month ago and decided I had done enough crying and I was sick of being negative about myself and it was time to take that doctor's advice from Nothing Compares 2 U and try to have fun no matter how. So I wrote about sex. In a jocular fashion. Making something funny out of a subject which was painfully on my mind. I had fun. And from the moment the piece was published I had nothing but fun. I laughed and smiled, I forgot all about my woes."
