Every Medication Failed so far

I think my crohns is starting to flare again, as been in quite some discomfort and pain the past week. But I'm without medication as everything has failed so far to work. Over the years I have tried various medications such as Pentasa (didn't work), azathioprine (which damaged my liver), adalimumab (which worked briefly but I built up antibodies to), Infliximab (which I had a severe allergic reaction to) and then recently tried ustekinumab which again badly starting damaging my liver so had to stop.

Since being diagnosed with crohns over 12 years ago when I was 18 I have had 8 Surgeries for it, have had 2 stomas (Had it reversed and had to have it again after falling ill again), had multiple fistulas which were so painful and I couldn't walk for like 2 years becuase it was touching a nerve that went down my leg.

I'm just scared theres no end. I have been battling this horrible disease my whole life and roughly have a flare up every 8 months upto date which mostly ends up in a hospital visit and a high dose course of steroids to settle it. I am now worried that I have exhausted most options when it comes to medication as the most recent medication I tried was brand new and only just got funding for it.
