I hope that everything is fine with you,

I'm posting here because it's really hard for me at the moment. I have been suffering from diabetes since I was 12 years old (I am now 26), and I have always been poorly controlled because of the fear of needles. I've asked every consultant I've had to deal with to review the pump, but they've never done it, now I'm really starting to struggle. I have a vision-threatening retinopathy, a trigger finger on both hands, a wrist tunnel, IBS, severe depression and anxiety, and to top it all off, I recently discovered a tumor in my chest, which I'm checking in a few days. I'm really starting to have a hard time coping. All the pains and ailments become simply unbearable, I am so tense. All I do is worry, and I feel like it's starting to affect my relationship. Does anyone else suffer from health anxiety? And if so, how are you coping? I'm so afraid I'll go blind. Any help would be greatly appreciated, thank you for taking the time to read this
