As you can see already, many of us relate. A lot of people struggle with emotions like these at some time or other in life, with varying degrees of intensity.
I have struggled with loneliness and self-hate for as long as I can remember. Some days and times are much worse than others. I too work with a T, and he knows these things. His advice to me was pushing myself to focus on other, positive things in life that I can see. Not turn a blind eye, no. Recognize that my loneliness is still there, but, look at the flowers! {Flowers, and nature bring me a sense of peace inside. That's why the flowers were recommended.} The flowers are still beautiful. They do bring me some sense of fullness, and understanding. It isn't perfect, no. But I can bear those feelings that challenge me.
In general, the technique works for me. I often lose myself in nature, so I can feel that release inside of me. Whatever works ~ as long as it's isn't harmful! Right?
Gentle hugs to you!
