How do I start to live a life without the person I can't live without?

Start putting yourself out there. Change your mindset about the situation. You're saying that you can not live without this certain person, but that does not have to be true. Get up and go do things to get your mind off of them. Start meeting new people or getting together with friends. You will soon see that you do not need this person in order for you to be happy with your life.

Learn to love yourself is very important. Keep on the positive side on what you can offer to others.

Find new hobbies and meet new people. People come and go but it is important to focus on you. Do some self care.

Although starting a life with someone you cannot live without may seem hard at first, it's important to understand that you control your own life and you are the one that will live through it forever. I personally think that putting your hand your fate into the palms of others may be unhelpful to your growth as a person. Starting a life by yourself is a daunting experience, especially if the person you want to be there is not there however, understand that your fate lies within your own hand. It is positive to try to understand that the life you want to live is within your control and having someone else there may possibly affect the best path you want to take in life.

The most important thing is not how you do it, but that you do it. Start living, eat, sleep, study, meet people, whatever suits you. Eventually you will start feeling alive again. First of all,to have a mindset that you cannot possibly function and live life correctly without somebody else,is extremely unhealthy.You need to learn how to love and take care of youself as well as be able to do things without the complete dependency on another person.Nobody else is going to know exactly what you feel and need at the exact moment except you.You're the only person that will heal and carry yourself through life no matter how impossible and lonely that sounds.Do not give someone the power to make you feel like you can't survive on your own.People leave and you're the only person that will stay with you so you might as well live life with yourself and depend on yourself and love yourself because you're going to be stuck with you for the rest of your life.

Whenever someone has left me, I focus on what life was like before they entered it. And find a positive point

I think it comes down to knowing yourself and loving yourself. You truly have to cultivate a relationship with you: physically, emotionally, and spiritually. It has to start here.

Take it one hour at a time. Then one day at a time. Be gentle on yourself but remind yourself every morning that you lived before them, have lived separately from them, and you can live without them. Pursue your hobbies and passions, develop yourself into the person you want to be. Explore new things and chase your dreams. One day you will feel like a whole person again.

It is difficult when you first start off living with someone you can't live without and I'm sorry to hear you're going through that. Perhaps do things that you enjoy, find things you like and new hobbies - I'm sorry if I sound cliche but it does help, surrounding yourself with positive friends and meditation may be of help too. I hope things become a little better for you soon. Sending love.

It'll take time but just take it one day at a time. If you're reading this, I'm sorry about your loss. Maybe you could try picking up different hobbies that you never got to try. Maybe travel to new places or meet up with new people. If it's possible, try to get some professional help if you believe that will benefit you. Try meditating to calm you down in your bad times. Lastly, try to be patient with yourself. Understand that it may take a long time for your wounds to heal and they may not ever be healed. You may always have that pain in you but I promise the wounds will patch and fade until they're nothing but a distant memory.
