Sorry to hear that u have such difficult life circumstances! My heart goes out to u. Hashem is waiting for u to cry out to him! I do not to minimize for one second the magnitude of your pain! Maybe this will ease some or your pain.
I have heard directly from an internationally famous Talmid Chacham,one of the outstanding Torah teachers of our generation,the following advice for dealing with such overwhelming distress. His instructions are as follows:
after Shacharis say the following short Prakim of Tehilim (13 and 142) then say the following prayer to Hashem (not on Shabbos or Yom Tov). If the Hebrew is too difficult, they could be said in English.
"Ribono Shel Olom,ayn ani mevakesh elah rachamim"
translation Master of the Universe,I am only asking for Divine Mercy".
btw (my own comment) What a better time to cry our for Divine mercy than this month of Elul,when Hashem wants us to come close to him.
