Does it make sense to feel further from people after talking to them?

A lot of people in my life are trying to help me right now. They all keep wanting me to “spill my problems to them,” so that they can help me get “better.” I am not doing too great, I know. But I feel worse after talking to them. I feel farther from them. I feel more lonely. I feel more locked in my own head than before.
And then they are hurt, because they think that I am not talking to them because I do not want to talk to them. I do. I just hate the loneliness after. I cannot bear feeling any further from them.
Is this normal? What is going on? What can I do to alleviate that ache, so that I can open up to those dear to me more, and easier?
