I agree with the other posters: you've got plenty of time to sort this out, so don't put yourself under any pressure.

I'm not sure what else to say, because it is a difficult and emotional issue, and you seem very vulnerable.

If it turns out you are lesbian, you may find it difficult to accept. But you need to know that many lesbians are happy; many lesbians are in permanent relationships; many lesbians have children. These are the women who have accepted and embraced what they discovered themselves to be.
