Hey WePow. It is good to see you!
I am in a similar place in therapy. My T's philosophy stated in my words:
People must learn to meet their own needs. We can never guarantee that someone will be around to help us. It is perfectly okay to ask someone to help meet a need, but the other individual has the right to say no. We should be able to be okay even if the person asked says no.
It's not easy. Even the healthiest people need people sometimes. Most of the time, if you have good friends, family, significant others, etc., someone can help you. That's why it helps to have a solid circle. However, everyone finds themselves alone sometimes, and while it is painful, we can be okay on our own.
Good luck on your book!!!!
