So many things, losing track of what I need to catch up on, in life and studies

I just want to feel confident and comfortable enough in my own skin to not feel inferior around the awesome friends I have, and who care about me.

On a side note, I can't tell if I'm being used.. But at the same time I am doing it out of my own will, with only the intention of helping where I can since I have nothing much to offer as a friend besides my company.
