I think what I was struggling to communicate is my thought process of "its ok that this life is impermanent because I will still exist forever" doesnt quite feel like acceptance, but some type of avoidance. Unsure if I should be deeply analyzing my beliefs.
Materiality/form is what is impermanent. Energy is permanent, as per the law of conservation of energy, which states that energy can neither be created nor destroyed; only changing from one state/form to another.
Reincarnation is the belief that best combines the awareness of eternal soul/energy with the impermanence of form and the material body. If you are able to realistically contemplate the possibility of soul/energy transmigrating from one birth/body/form to the next, you will have reconciled the otherwise conflicting concepts of the eternal and the impermanent.
According to the Tibetan Book of the Dead, there are monks who have maintained conscious awareness throughout the process of dying and becoming reborn into a new body.
The benefit of having this awareness of impermanence combined with the eternal is that you can live in the present with a sense of being part of an eternal future that your soul will continue on within. In other words, all bodies die at some point but souls are experiencing the effects that they helped cause in past lives, so that should motivate you to live for the future beyond your own death.
Another realization you can get from contemplating reincarnation is that there is no sense in hastening progress toward death by self-destruction in whatever form. The law of karma requires us to undergo whatever suffering there is for us to go through, whether we do it in this life or the next. So as unpleasant as life may sometimes get, we should realize that suffering is also always temporary and that enjoyment, which is also temporary, occurs as the flip-side of suffering.
Ultimately, then, happiness comes with the awareness that we have to continue moving between relative/temporary suffering and relative/temporary enjoyment; both up until death and beyond it.
Hope that helps. Expanding awareness of the greater nature of things can be both stressful and awe-inspiring, so be sure to take it slow and don't drive yourself mad with contemplation in any way.
