SMS, first I think you should define exactly
what would make you happy. What are your interests, hobbies, passions, and dreams? This might require you to do some digging inside your soul, but when you close your eyes and picture your ideal self, who is that person? What does she look like? Who are her friends? Who is she dating? What is her job? What are her hobbies? How does she spend her free time? What spiritual path is she on?
I read once, a long time ago on this forum, about life visions. Basically they are descriptive pictures of your life, written down in a private area for you to read each day. You write down your goals for relationships, work, family, finances, emotions, social life. Describe these things in extreme detail and list exactly how you want it to be as if these things have already happened to you.
Example: I have an amazing job as a teacher and I help children learn math each day. Additionally, I help give them confidence, love, and etc....
You can insert any profession that you'd like.
For a relationship it might be like this:
I have a boyfriend that I love deeply and we support eachother completely. We are both lightworkers. We like to go to the beach together, run together, and we have a dog...
I think you get the idea. I created a life vision and I get excited just reading it. Read this every day and eventually the Law of Attraction will take hold for you. It takes time, and you should probably do more research on Intention and Manifestation.
I was similar to you when I was younger (I'm 24 now). I was quiet, anxious, angry, introverted, not very social, completely unaware of who I was inside and what I wanted for my life. Now I can say I've done a 180. I have a great boyfriend, tons of friends, a lifestyle that I love, dietary habits that fit with my values, an education that I enjoy working on, and a great relationship with my family.
You can have this too, I'm sure of it. There was a time when I never thought I'd get out of my funk. But guess what ~ you are out of it!! Just as soon as you realize that every passing moment is another chance to turn it all around. Good luck to you and I will be thinking of you!!
