Before you can be in a healthy relationship, you need to first know who you are individually!
You should not be with another person to lean on or expect things from that you cannot first do for yourself. Learn to be alone, to enjoy your own company, think for yourself, provide for yourself. When the time is right, it will be the perfect time to enjoy yourself with another person. You should not have to rely on someone else to be the best you can be. They should add to your life but should not replace it. You need to seek a compatible partner not one who makes you feel small or is anything negative to your being. Keep in mind that if this kind of person you do find, your stress levels will be so dangerously high, you start to lose control of the person you truly are and are able to be.
With that said, the value of someone positive and special in your life can reduce stress greatly in your life! Huge endorphins and a feeling of joy in a healthy relationship is one of the most unique feelings you can find in life. It raises a higher sense of commitment, patience, understanding and purity within our beings and keeps us grounded while adding huge energy and excitement to our lives. It is hugely powerful when two human beings come together with all of their own personal strengths, confidence and positivity. What a tremendous sense of joy, wisdom and happiness that will create!
Seek that special someone to share in your joy, but learn to not lose your own self along the way.
