I Feel like nothing is meaningful anymore in life after a breakup.

I have broken up with my ex of 5 years and I feel as if my life is gone, I don't have the spark for life like I used t, I recently bought a new motorbike (Yamaha R1) to feel the thrill of life again but since getting it I use it as more of an ending of life excuse and a way out of my head noise rather than enjoyment. I'm just feeling so much pain and not sure how to deal with my head noise atm in the correct manner.
