I know that you've probably heard it said before that you need to love yourself more, or that you need to learn to love yourself before you can love anyone else. I promise I know the struggle. You are not alone; there are other people that struggle with acceptance and self worth every day. It may not be a big deal, and then again it may be. It depends on who you are and what exactly is making you feel this way. As a person who has struggled with loving them self for a long time, I have been able to conclude a few things about what kind of actions to take.
If you struggle with loving yourself, ask yourself why you feel this way. Make a list, write it down. List out all the things that make you feel like you are less. if there is a person on that list, get them out of your life as fast as possible. If it's family, talk to them. Sit down with them and tell them how they are making you feel, and I almost guarantee that they will do their best to help you not feel that way. If it's friends or boys or other girls, tell them to take a hike. One of my favorite quotes ever is:
"You don't need people who don't need you."
Take that with a grain of salt and move on. If someone makes you so miserable to the point that you question your self worth, they aren't worth you time. I struggle with this currently, and I can honestly say with 100% confidence that once you rid yourself of these people, life is so much better and you will feel amazing.
If you don't love yourself because you think you are overweight, then go exercise or pick up some healthy food when you go grocery shopping. If you don't love yourself because you aren't sporty or artistic, then go practice. You get out of something what you put into it. You can not sit around and expect to wake up one day in love with who you are if you do't change the things that you struggle with now. Be positive and tell yourself that things will change and it will get better.
Rid yourself of anything in your life that makes you sad, and focus on the positive things. Start a journal, take a hike, go swimming, read a book, start a blog. Take some time for yourself and figure it all out. Don't feel rushed to figure everything out either. You might be stuck in this in-between feeling for weeks or months, but I promise that self-acceptance will not happen overnight. Take your time, and develop from these negatives.
I can say this: it gets better. It may not seem like it now, but I promise that it will. Be patient and understanding, and you will find your happiness.
