Suicide, right under the right circumstances?

[loser]

Okay, so I know everyone will say, don't do it, you have something to live for, it's selfish, or that legally they can't say yes. But what if you really don't have a reason to live, and are just a burden to your family and society. I am 32, I live with my parents, I don't work, I have only worked a total of less than 3 years my whole life. I am on Social Services. I have never had a girlfriend, or sex, not even gone on a date, or been kissed. I have no friends near me, and the friends that I do have, don't seem to be missing me, since I am the one who does the calling, or emailing, and most of the time don't get an answer. So I know I'm not going to disrupt their lives, except for a day or two for funeral services. I spend all day trying to find ways to improve my life, but nothing works the way it does for everyone else. I am miserable all the time. I am in therapy, but it doesn't seem to be working. So my question is, is suicide really okay in my situation. I have tried a few time, and can't even get that right.
