Spondylolisthesis & pars fractures

Hi anyone!
Im a 37 year old female who has had a painful lower back for over 10 years, ive been to several GPs over the years and sadly never been taken seriously, i was told it was “age” and to take pain killers.
The pain would come and go but at the beginning of the year it flared up and didnt budge at all (and still hasnt) so i took myself to the GP again for one last attempt only to be told back pain is no longer seen by the doctors and that i had to self refer to Physio which i did, i did a block of physio for around 2 months which didnt help in the slightest.

Thankfully the physio was extremely helpful and arranged for X-rays and a scan that showed i have Grade 1 Spondylolistesis and referred me to the spinal team who i saw this morning.
During the appointment i was told i have pars fractures which is what has caused the vertebrae to slip forward, he told me “if i was younger id be able to have an injection” but as it stands theres nothing he can do, that spinal surgeries dont work so thats off the cards, sp basically i have to take pain killers and put up with it.
Im devastated and frustrated im in so much pain every single day, i cant sleep, Its painful to sit or lie down for long, if i walk for longer than 10 minutes i need to constantly bend over forward to relieve the pain & pressure.
Im only 37 i cannot live my life like this, i honestly dont see the point in carrying on.
If anyone has any experience with this or advice id be so grateful!
