Absolutely do not commit suicide whatever you do. Even if you DO commit suicide, you will not escape the problems that plague you. You will incarnate again with these exact same problems and face these challenges all over again. There is no escaping your karma. You
must deal with it. No matter how bad things may seem, know there is always a light at the end of the tunnel. I feel you are focusing far far far too much on the material and petty "love" issues and not enough on the spiritual and that this is a big cause of the problems you are having. I distinctly remember you saying you have a Leo moon and how you have star-quality and want to be an actress. You must learn humility in this life if you are to do anything of value for humanity. Arrogance is a product of the Ego and you must realize you are
not your ego. Your ego is simply a temporary personality you have created in this life to survive the harsh 3d reality we live in.
You are only just barely 17, there would be absolutely 0 point to you ending your own life when its just barely starting. By doing so you will void your soul contract and not be of any use to Earth or her denizens. Remember, a negative attitude towards life will attract negative outcomes in it. Your negativity must be quelled and stymied and replaced with positivity in order to counter act the bad things happening in your life. There are 2 base emotions humans operate on: Fear and Love. You are currently operating on fear. This is the antithesis of a good life and you must switch to love if you are to fix your problems. Hold on to hope and ask your Spirit guides and Angels for help and guidance and trust that they will help see you through to a brighter day.
Pray to God/Spirit every day and every night and be thankful for what you do have, not longing for what you do not. If you wish to fix your circumstances you must first fix the problems that are inside of you because the outside world is simply a reflection of the inside one. As above, so below. As within, so without. Your life will improve once you improve yourself. Trust all will go well and it will
Have a wonderful weekend!
