He is there for you and He always will love you. So when things are challenging, look to Him. He is probably the Reason why you are where you are. Look up and ask Him to intervene in your life and make you whole and happy.
The further you get away from Him the worse things become. So stay with Him, in His Word and talk with Him daily. He loves the attention you give Him and loves you so much. He is the Reason why you are here to grow and love and be closer to Him.
So when others around you are tugging at your patience, your doubts and everything negative, remember that He, that One that is so Positive, is the One that is shaping you into who you are in Him.
Finally, He is there so ask Him to cleanse you and make you into who you are in Him. You need to make the effort and have that positive attitude and be happy for all you have. He loves you and knows you can do it.
