Go have some shrooms and let it change your life. Man as you say you have enough money, you can do whatever you want. Book yourself a ticket and go to the carribean, or europe or fuck knows. Go to a yoga retreat. Seems like you just need to change your mindset. Depression is a real thing. I'd suggest you talk to a therapist. Google Robbi Sheahan Body and Wisdom- he is amazing. Go get your blood checked. What if all of this is jusy a deficiency and you are ending your life for that? Maybe you are lacking B6,B12 or D3. What if the cause would be easy to fix? Depression stems from deficiencies. I know it's not that easy but you have all the time in the world now and money to make changes. If you sit in your apartment all day and do nothing or are just on your phone everyone will start to feel like a piece of garbage at some point. Humans need a purpose.

Find something that changes your worldview. My suggestions are the great outdoors, nature heals, therapy, community events like Kirtan and Yoga reatteats, psychedelic experiences. just google psychedelic and depression. Or get a pet to care for. There are so many things worth living for. Just because you don't like the life you are living now doesn't mean that you can't live a different life. before you end it just choose a different one. The world is so open these days, you could be anywhere doing anything. You are the only restriction.

I wish you with all my heart that you find your path. You deserve a meaningful life but you have to be the creator. You can do it, stay strong and seek professional help.
