You are here because you made some classical mistakes that probably everyone makes in their relationships. Namely going into the relationship expecting it to work out just because you think you are 'special', while in reality a guy can pack his bags and leave any given day. You opened your heart 100% leaving yourself vulnerable and exposing yourself to emotional hurt by letting your happyness in life depending on him was a grave mistake to begin with, what you are going thru is normal after a broken 'i dare say shattered' heart. Even so because i did the same 'suicide attempt'
But a little voice in my head said 'this is a too easy way out, and not the right way into dealing with your problems in life.
Bring the power of your life back where it belongs, namely in YOUR hands. Many people hide in a closet and cry over their lost loved ones putting their entire lives on a halt.
What you should realise is that you shouldn't put your life on a halt when something goes wrong. If you are in a rut and stuck with your life, you need to give it a swing in a new and positive direction by carving a new path with your own power.
Do not expect leperchauns to appear and solve your issues, do not wait, be the dictator of your own life and take the situation in your own hands.
There are only three directions in life, down where death lies, stay where you are and go in circles, or up where an improved life lies ahead, the first 2 are worthless and lead to nowhere, this is important because it means you can set the course of your life, to the only direction that is valuable ,namely upwards towards into progress. It doesn't matter from there on wether you win or lose in life, you simply keep on following the positive course, that way you can ALWAYS be confident no matter what happens, because you know that going for gold in your life is the only right way to live.
If change was just a thought, then anyone could do it. But reality is that you can't just sit around feeling miserable for yourself and the situation you are in while being punched in the face by the reality of life. Those thoughts of change, can't become real if you just sit around feeling sorry for yourself, if you want to change then why would you stay in a state of paralyzation? If that happens it means you do not want to change, you are simply waiting for the world and people to change around you as you see fit, therefore
Without walking, there's no way to move forward, you'll just end up waiting.
You need to be like a castle gate closing yourself to bad people/things/events, and open yourself up to good people/things/events, if you let the enemy into your castle they will only end up destroying it(even if its family), and leaving you crying over the ruins.From there you can keep on crying, or rebuild your life, i advice you to rebuild your life.
You need to realise that you can only love someone but you don't own that person as personal property, you know many people shut down after a bad experience totally against everyone and everything. Nobody wants to be with a sad person (although i seriously doubt they are real friends of yours, simply because a real friend steps into your life in times of trouble while fake friends step out) and that's why people are leaving you, it might be a time where you get to learn your real friends.
You have your own free will , God doesn't arrange who you date, or who you marry, thats your own personal choice, many people see God as their personal dating counceller, who is supposed to bring 'the one' into their lives, the bible is not a dating book, rather a spiritual experience in which you learn how to save yourself.
The false door of suicide is always the wrong choice.
As said try to give a swing to your life into another direction. Have a life of your own to start with, that way if a guy jumps out you can rely on yourself instead of being an emotional soccerball for others to play with.
Don't blame your parents. Don't blame god. You are responsible for who you are. If you want to change who you are, do it. Blaming your genes or your invisible friend and continuing to live the lifestyle you hate will get you nowhere. Accept that you dug the hole you are in, now you've gotta pull yourself out of it if that is indeed what you want to do.
There is no failure except in no longer trying.There is no honour in giving up. There is no defeat except from within, no really insurmountable barrier save our inherent weakness of purpose.
Negative thoughts can lead to indescribable suffering ,so start to think and doing positive.
Do something non-destructive that makes you happy, then next week repeat that, and add another thing that makes you happy, rinse repeat until your entire week is filled with things that you love to do. That way you balance out your happyness over the negativity, and then you'll learn that rejection is a part of life, that you have to get over.
At this moment however i advice you to pick up the broken pieces of your heart, and mend them together, and give yourself time to heal, i advice you see a counceller, and talk talk talk in here about your daily odeals in order to process all that what has happend in order to recover and be moveable again in your life.
It's hard isn't it when your boyfriend decides he doesn't want you any more
