Not a problem, and thanks for the welcome back.
Also I find that it is sometimes good to try to remember the good times that one had and to see that they did have good times in life and to try to draw from those feelings and to try to understand that right now it might be dark but there is plenty of light out there, one has to try to tap into it as much as possible.
Also saying Tehilim in general is good and especially if you have in mind a specific choleh or all cholem in klal yisroel and it gives you the feeling that you are actually doing a chesed For someone.
I once read an amazing story about Tehilim which I will share with you.
There was a certain woman who made it a habit that when she was in a stressful situation in her car (i.e. traffic) instead of getting frustrated she would say Tehilim. One day there was a lot of traffic and so she did the usual, she took out her Tehilim and said some Tehilim. As the traffic eased up she saw that the cause of the traffic was a car accident. As she passed the scene of the accident she silently thanked Hashem that it was not her and she went on with her life as usual. A short while later she was in some sort of office (Doctors office or the like) and a woman came over to her and asked her if by any chance she was near the scene of an accident recently? She thought back and remembered the incident mentioned above. She told the other lady that she remembers being at such and such a place and there was a car accident but she did not think much of it. So the lady told her you should know, that I was the one that was involved in that car accident and I recognized your face because my neshama started ascending to Shamayim, then suddenly a whole bunch of letters started to surround my head and slowly slowly I felt myself being pulled back toward my body, and believe it or not the letters where coming from your car.
Sounds too good to be true but it is supposed to be a true story that I read in one of the popular books. Just shows you the power of Tehilim. Sort of like the lotto, hey you never know.
Don't forget Chanukah is around the corner so hold on tight. Hope things brighten up.
