I am sorry that you are having a difficult time. It is important to put your situation in perspective. Your life was likely not always as difficult as it is now. You are facing a challenging time. Your father is dying. You recently moved and have begun college. You are in a new town and you don’t know anyone. Virtually anyone faced with that set of life circumstances would be struggling. It is understandable that you feel the way that you do.
Having said that, is important that you know that suicide is never the answer. Yes, your life is difficult but it will not always be this way. You predict that it will be so but have no evidence to support that prediction. Depression has a pervasive effect and will result in negative predictions of the future. Ending your life is not the correct solution to your problem. The only appropriate solution is to seek professional help.
Almost all colleges and universities in the United States have mental health professionals on staff. Those services are free of charge to all registered students. I would encourage you to locate the counseling center on campus and make an appointment immediately.
Now, most of all, you need support and counseling. I hope that you will seek professional help. If you feel that you might harm yourself, go to the hospital or call 911 immediately. I wish you the best of luck.
