Hi cutegen. I know how you feel but blaming god/allah did not do it for us. It is as humans that makes our life too depressing. Do you have a hobby that you can join to make your life occupied? Join a volunteer group, martial art is a good mind and body reliever also. Do not despair life is not that bad. We just make it happenned to us. It is all up to us to control and learn from it.
Unless it is a chemical embalance problem then maybe you need to go see a doctor that can prescribed you medication to help you out. Think positive. Always associates yourself with people that have goals and learn from them. Life as we go through it is so hard but god/allah can only give us enough problem that we can tackle. I think god/allah do this to us to remember who we are while we travel in this hell hole I called earth. I know myself I will not let life gets me down I have been through good and bad in life but through faith and hope i always think that i am so fortunate to be able to think positive and overcome all the bad things happenned to me and the good ones I thank god/allah everyday for being alive and kicking in life we are fighting for. God bless
