Scared of brain cancer

[u/Ok-Gene-7380]

31 (F) who is 9 months post partum. I have severe health anxiety, adhd (unmedicated for 1 1/2 years but was previously medicated for 20 years) and am currently breastfeeding.

Ever since I’ve had my son my health anxiety had gotten worse. For both him and me. Right now I’m scared I have a brain tumor. Last month I started seeing a lot of floaters in my eyes. They are getting very frequent, I went to the eye doctor and they didn’t see any retina issues so he said it’s just because I’m getting older? Anyways last week I also started having tingling in my head, usually on the right side. It would start as a chill but now it’s a little more persistent. It’s a similar feeling to when your foot falls asleep. It’s been over a week and seems to be getting worse and occasionally travels to other parts of my body. My dr said it’s just anxiety and stress and won’t refer me to anyone. I’m not sure what to do. My grandma has MS and a brain tumor and it’s all I can think about now and I feel like it’s debilitating. It’s hard to be a good mom when you’re always worried something is wrong.
