I am a year younger than you, have had BPD problems my entire life, never even heard of BPD until this past February, and was only diagnosed for certain a few weeks ago. I understand; it's very, very frustrating. If we'd only known sooner...but we DO know. Imagine the amount of people our age or older who've had issues all of their lives and don't have a clue. Don't give up. Get involved with DBT...there is a free class on Yahoo at
http://health.groups.yahoo.com/group/dbtclass/. I often feel the same way...my life is half over and only NOW do I know, but at least you do know, so now you can fight. Use this forum to give you support and the will. We all have the same issues and help each other as best as we can. It's hard...not going to lie, but there is hope. Don't give up on that.
