Hope that in the end there will be a sigh of relief

Today was my last day of this semester. I feel quite depressed though. I don't know why it is but it is very prevalent right now and I am not feeling good. My family is in the middle of a move from house to house and that may be stressing me out. But I am still afraid of the thought of suicide. This often is the feeling that there is going to be relief and an opening in the sky if I was to choose to end my life. What would I be missing? I have no friends, just people I sometimes meet in school... I am so worried about my debt and what I want to do in the future because I want to be happy and successful. But how long am I to wait? and with my insurance I need a job that can give me a new job wit great benefits. So wouldn't it be better to overdose and simply fall asleep and drift away with no pain and no emotional details. I just need to research how much I would need to take for that. I took 6mg of xanax about an hour ago and I am just feeling a small bit of relaxation. But, moving the relaxation and depression together makes a big difference. I am not scared of death I simply want to know about it and weigh what may happen. I dont know, now I am really tired! 
 
Goodnight Moon.
