God can't hold me or speak to me audibly (or maybe he only does that to the super-spiritual). He doesn't need me for anything. He may love me but he loves everyone the same way, so how is it any different from any other person?
You're so young and there's so much to learn from living life. There are so many people, including myself, who have felt like God wasn't listening to their prayers. Honestly, it took me until the age of 30 to recognize how God works (and no, it's not audible).
For me, even though I grew up in Christianity my whole life, I didn't truly understand what it meant to have a relationship with Jesus/God until I was 30 years old....and desperate. I was single, pregnant, let go from my job when I was six months pregnant with absolutely no idea how I was going to support myself, much less a child.
I finally told God that I was ready to do things his way, to live my life the way he wanted me to, and to spend more time developing our relationship through the Bible, worship and lots of prayer. It worked, but I have to admit that my faith was a little shaky until Jesus took me by the hand in a dream I had and told me that he would always take care of me and life wouldn't become the struggle that I anticipated...and it wasn't. That dream changed my whole outlook and my faith was stronger than ever. Without going into all of the little details, shortly thereafter, a check from a previous employer's employee stock ownership plan came to me in the amount of $12,000 to hold me over financially until after I gave birth and found a new job (approx. 6 months later).
It still took a while for me to meet the man of my dreams. I stayed steadfast in my faith, raised my daughter the way that I knew God would want me to for 10 years before the person I was always meant to be with came along.
My life is finally everything I dreamed it would/should be, but it's a journey, and it's one that I guaranty that you won't find fulfilling unless you include God in it.
Once you start developing a true relationship with God, you start to notice how he works. He sends other people into your life to help you and he protects you from everyday harm and hardships, but I'm not going to lie, I thank Him every single day for everything I have. My health, my family, my smooth running life with all of my bills paid, my cars running, and able to pay for the college education of two kids. This is more than I could have ever hoped for back when I was single, pregnant, jobless, alone and desperate.
As someone else mentioned previously, this life is temporary. Build up your relationship with God now so that you can experience not only the best life has to offer now, but the eternal one that's offered after this human life is over!
God Bless!
