Christians,So am I having spiritual warfare?

Ok,I am a christian(just rededicated my life to God). I am suffering from anxiety problem and insomnia due to fear of sleeping...I feel insecure,anxious in everywhere I go...I have alot of fear in me-fear that people around me dont accept me as I am ugly and mentally retarted...I feel that I got mental problem....I dont have the ability to think positively,eg,when I am feeling depressed and read the word of God, I feel that the words of God are LIES and not true..I feel that I have no future and feel that my depression,anxiety problem and insomnia will nvr get heal..Suicide could be the only answer to me....I have fear of sleeping also...when the night comes,I start feeling insecurity and feeling that I will never sleep well.
