But it can become too late

time is running out. You can only achieve certain things within a certain window of opportunity, once that has passed you are physically too old, with too little experience and skill to complete what others have completed decades before you.
Success = Work + Skill + Luck
I have no luck and having BPD doesn't help in that regard. I try to work at building my skills, but my skills aren't improving - they are in decline.
Who would want to hire a 30-year-old woman with a degree (that she just got... a simple four-year degree that took her seven years to complete), who also has no positive work experience to reference, and a declining work portfolio if anything to show for at all?
I'm miles behind my peers and it feels like the harder I try to catch up the less point there is in trying to because the window of opportunity is closing. I'm 25 years old and I have nothing to show for my life, there's nothing except regret and mistakes that I don't seem to learn from.
I'm scared. I have so many dreams and I can see them dying in my hands, I'm so scared. When my parents die I'll be alone and I don't know what I'll do. I don't know where I'll go or how I'll cope. The future is terrifying and my plans to protect myself aren't panning out.
