not there

lately I  haven't been clinging to God, and that's not to say that I've been straying from Him, but I guess I just haven't been looking towards Him. I've been trying to put my trust and faith in Him and just feel that God is too busy for me. Almost as if He has no time for me. I ask Him for certain things and try to wait for a response but I just haven't been feeling God in my life. I feel as though I'm just a disappointment. I don't understand what I'm doing wrong. I'm trying and God knows I'm really struggling at this point in my life right now, and the one I can look towards isn't responding. I feel alone and useless. I'm trying to do better in school and in the one class I want to do well in, I'm not. I'm just trying to strive for the best I can be, for a successful career and even then I can't get a little bit of help. God where are You? I miss You. Come back!
