Am I addicted or misdiagnosed or both?

For about 30 years I have been diagnosed with either anxiety, depression, or both. About 8 years ago diagnosed with ADD via the IVA test, which made sense looking back at my childhood & adulthood. Then a PA told me I was misdiagnosed with ADD and that I have Bipolar depression, which also made sense because the symptoms are very similar. Additionally I have used sleeping pills for 25 years, started out on Ambien, but it now takes 30-50mg to help me sleep. Tried Benadryl which only worked temporarily, then Ashwaganda which worked for
about a year then like the others, I needed more to sleep. Finally began taking THC pills which seems to work the best but again now I have to take from 10mg to 20-50mg and it’s getting very expensive at around $200 per month . There have always been times when I don’t need as much one night and then other nights it doesn’t matter how much I take, I don’t sleep. The Vyvanse for ADD definitely made sleeping more difficult, so I weaned off. It’s my understanding that if I have bipolar depression that sleep gets worse with age and if I am manic then sleeping medication might not be effective until the mania is controlled. The local behavioral health providers will just do whatever I tell them but no answers and no remedy? They currently have me on clonazepam every AM & Wellbutrin. I also have some mild sleep apnea which I treat. I also work in healthcare and need to sleep in order to function safely. I have considered weaning myself off all sleep meds but it’s never convenient when I need to be at my best the next day. I have other health issues and have used all of my sick pay traveling to Mayo for appointments, so now, trying to get a correct diagnosis and/or rehab is even more difficult.
