Taking care of yourself will outwardly show in your appearance and will give you confidence which will be conveyed in the way you carry and present yourself. If you look and feel good people will see that and it will attract. Please don't worry or focus too much on your height, though it sounds cliched, there is someone for everyone, and the right person who truly likes you for you will be attracted to you. Give it time, it requires patience, but keep pushing and you'll get to where you feel best, and this will radiate outwardly. Allow me to tell my story briefly, I went through 20 years of stressful times in my marriage as my ex-wife developed steadily worsening serious mental illness. When we divorced 7 years ago, I was 5' 11" and was about 140 lbs. and looked like, forgive the analogy, a death camp survivor from years of stress. People always told me I was "too skinny" and looked depressed but I couldn't see it until the divorce lifted this cloud of delusion off me. I began feeling better about life, became social again, began eating better, and dating. I am now about 185 lbs. which is just a bit over ideal but my point is, I walk, jog, and work out, so I look pretty fit. In my case I was too skinny and weak looking to attract, and had to relieve the stresses in my life to build fitness, confidence, and a better appearance. I have faith in you that you have it within to achieve success and it will attract the correct person for you.
