Your confusion and feelings mirror my own. I feel like a misfit at work as well. Almost everyone is coupled with someone. They're well adjusted, successful. And then there is me...and I'm just...problems. So many problems.

I can't really give you advice on how to cope with this, because the solutions elude me as well. But I wanted you to know you're not alone in feeling this way. Talking and getting it out of your head is definitely good for you. Like you, I'm a quiet person and don't openly talk about my problems with anyone. So places like this are a great place for an unbiased ear.

Keep expressing whats inside of you. Maybe keep a journal (I have a Captain America one!) and try doing something creative. I recently bought a therapeutic adult coloring book of geometric shapes. Bought a box of 96 crayons, and just work on it. Its very soothing, and with colors comes out how you're feeling on the inside. So its like inexpensive art therapy. The book I bought also has pages for journaling while you color. I got it at Walmart.

Find something that brings you comfort and peace. Drinking tea and spending time with my cat takes me to a better place immediately. Certain music does as well. I'll never forget telling my supervisor my problems, that I had a traumatic life, and he told me, "You need to find something that brings you peace. Think of a place, a person, a thing, a thought, anything, that brings you peace. And go there when you feel like you're losing control. Come back to control. Because you are always in control."

Hopefully this was helpful. Take care of yourself.
