will the pain stop

I went out with some friends last night hoping it would cheer me up and it did 4 awhile. But woke up this morning feeling more sad then ever. Im so sad so angry so frustrated, i even yelled at my son 2day 4 no reason. I feel so stuck. I waant to ask my dad 2 look after my son for a few sdays but he already had him most of last week. Im so depressed i lay in bed thinking of ways to take my own life. I know im not being rational i get mad over little things and im taking it out on every1 around me. I feel so shut down in this world of pain and there will never be a way out. I just dont know what to do anymore. Will i ever b happy again. i dont know how to fix this
