I'd recommend a therapist or even the Anxiety and Phobia Workbook. I've used it a little and have liked what I did use. It comes extremely highly rated. One or both of those tools might be able to help you with your anxiety; understanding it, controlling it, and expressing it.

A side note, I found that when my now fiance and I were dating long distance, I was a lot more depressed and anxious, but when we moved in together, my mental health really improved. Now, I'm not sure if that has to do with the fact that we were finally together, or if I was feeling more adult because we were living together in an apartment as opposed to me living alone in college dorms, I don't really know. Perhaps I simply got a huge confidence boost having him next to me.

I've found that anxiety and depression tend to come with low self esteem and self confidence as side dishes. I think if you can work on these two things, maybe through therapy or journaling or positive affirmations, you might find that you feel less dependent on others for you own feelings of self worth. When you feel you are worthy of love, you might find that it is easier to talk about your emotions with less fear and anxiety.

Good luck and take care!
