I think something bad is happening to me…

Idk if this is the right R/ but I’ll try it. Full disclosure I have used hard drugs since I was about 19–I know red flag, however I’ve always been a functional user. I’ve always kept a job, relationships, money, providing a comfortable home and lifestyle for my family. I’m now 40. I’ve quit 90% of substances with the atrocious hit of crystal now and then and the far less insidious joint.
Where the problem lies now—I’m hallucinating.

Sober.

I often hear my significant other’s voice disembodied from her. It wakes me up. It’s vivid and real. I see things out of the corners of my eyes. Bugs. Spiders mostly. I turn to look at them and they vanish. Ummm my cat is haunting me…we had to let him go at the vet. He was so sick god love him. Now I feel him kneeding me sometimes. Or I feel his body weight on my bed. Or he’ll nuzzle. It used to be cute… Now it’s getting scary…he bit me…I know that’s messed up but I’m afraid. I’ve been to doctors and nothing is wrong with me… BUT SOMETHING IS WRONG WITH ME… Sometimes I see shadows or idk shapes…they’ll not supposed to be. Oh and I have phantom pain. One particular that starts in the middle of my foot and wraps around the sides—then shoots up to the ankle sometimes knee. It’s extremely painful and according to doctors phantom—there’s nothing wrong with your foot. I feel like I’m losing my mind…any thoughts?
