I know this hurts, but it doesn't have to be a bad thing. It's a normal part of the grieving process. No your parents weren't and no your therapist can't.

It's up to you now to make a life.

The way you approach the next phase will dictate the rest of your life in my opinion.

You can think of this as a really really good thing! A blank slate, a new maturity, and wisdom about your own efficacy and power in your life.

OR

It can collapse you into what never was. This choice, also in my opinion, is pretty much a death in life.

My vote? (should be obvious) Don't collapse. Grab the wheel of your own life and drive it like you stole it!

There are so many wonderful things in this life, so much love and hope to be had. Try not to focus on what you don't have (it's blinders) and LOOK, pay attention.

Be humble, grateful, and determined for what you do!

Life has its ups and downs, but overall, it's pretty freakin' awesome.

Go for it!

ETA: I know it may be tempting to say that you are just not ready for that step or I can't. However, that clock is ticking. The days of your life are numbered. Do you really want to spend it this way? You don't have to. It's controversial around here, but I contend, and will always do so, that you have a choice. Choose to live.
