Relationship anxiety

Quick back story: I'm a 26 year old single mother with a long history of severe anxiety and depression. everything makes me anxious and has held me back from so many things in life and mostly maintaining a employment and relationships. 

I am starting to worry that my fears will hold me back from settling down and finding the one I want to spend the rest of my life with. I have started hanging out with this guy who I have known but I still feel like I am so shy and anxious around him. I want to be myself but my mental illness has its claws in me and I don't know what to do! Has anyone else found it difficult to date someone? And are there any happy endings?
