I am looking for healing advice to help with my mental health journey

My name is Chelsea and I was diagnosed with Major Depressive Disorder in my sophomore year of college. I ended up going into an inpatient mental facility back during Covid after I rushed my journey by going straight from undergraduate school to graduate school and not listening to my inner self but to societal and familial reasons. I then got diagnosed with anxiety and depression. I have had crazy ups and downs, happy stories and sad stories and now my family thinks I have bipolar or BPD. This has killed me since my doctor doesn't think I have it and diagnosed me with ADHD instead which I always thought I had even as a kid. I need to prove to my family that I can take care of myself and that I know my body most. My family also has a lot of mental illnesses so their perceptions come out and confused my inner monologue and compass.
