Can you name some websites or forums that provide support, counselling, or programs for seniors dealing with the grief of losing their loved ones?

Processing the loss of a loved one can be more than just a challenging task, especially for seniors who live alone. Psychologists recommend seniors consult with and even go to therapy sessions with a professional when experiencing the loss of a close friend or family member.
There are not many safe communities online that a senior can rely on and vent to when they need to express their loss and collect their thoughts. However, you can ask a professional to introduce you to an online forum that can act as a safe place to express your emotions. If you undoubtedly need to vent, you can find comfort in Reddit’s “off my chest” subreddit.
