Removing yourself from this world is not an option. You have an assumption, an idea that 'it will be better on the otherside' - no, it will not, you have no comprehension of how much more difficult it is within the interdimensional existence, and don't 'think' that all your 'problems' or 'experiences' you have within you will just magically disappear - because it will not, it will intensify and then you will have to come back to earth, experience the exact same experiences you have now, much worse, to be able to transcend what you didn't because you gave up on yourself.
Thus - if you deliberately remove you from this life, you will and must return to another life, exactly the same and much more extensive to transcend what you wanted or attempted to run away from. Which will make your process two lifetimes longer and multiple times more intense and extensive.
Therefore, I'd suggest to stand up here, take self responsibility for you and not accept or allow the mind to dictate to you, who you are - apply self forgiveness and self honesty in every moment - SELF FORGIVENESS IS THE KEY - so apply it.
Here are some perspectives we have given to beings who believed or had a perception that it'll be easier in the dimensions and who believes or had a perception that they can actually run away from themselves = there is no escape from you, you will face you and I suggest you do it here - not in the dimensions:
