Hi,
I was 19 when I had my Spinal Fusion T2 to L2. It is difficult on an emotional level, but you will get through it.

At the time I had my fusion, they placed me in a cast for 10 months. That was the most difficult time and was the biggest disruption to life as I knew it.

After that initial period, my spinal fusion never impacted my social life nor did I ever have as any problems dating. You will get to a point where you will forget about your spine surgery. (But you must follow the guidelines your doctor recommends as it relates to activities.)I remember dressing in a locker room once and someone asked, "what happened to you," and I had no idea what she was talking about.

Throughout your life, you will get a ton of compliments about your posture
You are just 8 month post op so some of the pain and nerve related issues will probably go away. But, if you haven't done so already, be certain to let your doctor know about the pain and nerve sensations.

Things will get better! I have no regrets about my spinal surgery and I never had any problems with that part of my back.
As gikes1 suggests physical therapy is key to your recovery and you should be doing the exercises you learn in therapy throughout your life.
Best Wishes!
Nadine
