Assalam Alaikum brother Rabbani2005,
First of all i would like to tell you that in everybody's life good and bad times come,but its cowardness to think of taking step of suicide when bad time comes.what you think if a person suicide himself will he be get rid of his all worries.no not at all.u must know that suicide is strickly forbided in islam.
Now think positively.dont be dishearted Allah is very merciful and loving.so you should ask forgiveness from Allah with whole heartedly,Allah will definetly make out the way for you inshallah.so set a firm trust in Allah
remember that in hard times every body can leave you but Allah will never,so do not do anything which make Allah unhappy ok.
brother NOW start a new hope in you!
hope you will take this as a sincere advice thats i can do,but i am sure your trust in Allah will solve the problem.
