dsesesy, the process of getting well and re-establishing your sense of connection to yourself and the world takes time and willful intention. You have to shed a lot of baggage that is standing between you and your happiness. You can start by stop comparing yourself to other people. I guarantee you that appearances are deceiving. The superficial world is an extremely poor indicator of what people are going through. There are entire worlds and dimensions happening inside of people that we can't discern just by staring at them.
If you feel close to death then you are in the vibration of shame. Guilt is the emotion that you've done something wrong, shame is the emotion that you are wrong. It's the experience of feeling unlovable, and that certain parts of you are so horrible that you should keep all of you hidden indefinitely. It's that part of you which is hindering your sense of connection. You need to start there... and debunk shame with some human compassion. Most of what people think is ugly and unmentionable inside of themselves is actually quite human and understandable. It's also not unique. I guarantee that whatever you're going through, someone else out there is too.
You need to start with a dose of healthy forgiveness. Forgive yourself for not living up to your own expectations, and forgive the world for not yet giving you what you want. The next thing I recommend doing is taking all of that guilt, sadness, anger, anxiety, and frustration, and hand it over to a higher power. Acknowledge that you don't currently have the tools and wisdom to see your way through this, and ask for help. Believe that help is on the way. It will then start to come to you in unexpected ways. Have courage, have faith, and above all be patient. Not only can things change, they can change faster than you realize. In a year from now, or even a month, you could be on a different path.
The death you are seeking is not literal death, it's the death of all the egos and mirages in your consciousness that are preventing you from seeing clearly.
