Honey, all anyone can tell you is don't give up. Everyone experiences failure. Everyone! Some of us never even get off the ground!
Embrace your failure. I'm willing to bet it has taught you A LOT. Take those lessons and start over bigger and better than before. This is an opportunity. Get excited! This is a chance to improve and grow. If you simply hang your head and say you've failed and give up, that is the only way it will have all been for naught. Giving up is the only way you can ever guarantee true failure. I know.
Aside from that, you may consider a bit of research on asset allocation for the next round. I don't know what you invested in, but perhaps next time you need to be more diligent about putting more secure investments in your "securing my future" basket? The higher risk stuff is good for growth, but not good to hang your future on.
Yes, I'm not an expert. However, I'm becoming quite fond of listening to them and taking their advice.
Just remember, this is a bump in the road. It is NOT the end. It just means you have to adjust your course and get back out there swinging. Good luck to you.
