Roebuck did not play for Manchester City again after her stroke but she was able to complete her dream move to Barcelona in the summer.
Yet she says the way her final season was handled at a club where she made more than 100 appearances left her confidence “diminished”.
“I just felt like maybe my relationship with the manager [Gareth Taylor] got fractured.
“I don’t know whether that was me, maybe not hearing the clear communication or the fact that there just wasn’t clear communication.
“I got my head down and I just tried to work every day, but I think it was a badly managed situation. I’ve always been professional. I just felt like the respect wasn’t reciprocated in that same sense.”
Roebuck says that while she was “devastated” to leave City, it made joining Barcelona, who have won three of the last four Champions League titles, a very easy decision.
However, she admits that her first training session with the club after six months out was a lot more difficult than she anticipated.
“After coming back from having a brain injury and then saying you’ve got to dive at someone’s feet, it’s not the prettiest. But I had to get through it.
“Barcelona showed trust in me and for me, that was more important than anybody saying you can have a starting role. It’s the fact they showed confidence in me, and they wanted me here and they want to improve me.
“The girls are amazing. The top three Ballon d’Or nominees are all in this changing room and it was a shock how nice everybody is, it’s crazy to me. I’ve never been a part of a team other than the England team that’s like this.
“So, for me it’s a perfect fit and I enjoy going in every day.”
Now 25, Roebuck made her Barca debut in December in a 4-1 win over Real Betis, 303 days after her diagnosis and more than 18 months since her last appearance.
“Everyone expected me to be nervous, but I felt fine the moment I stepped out there. That’s the kind of the mantra I’m going for, every time I get that opportunity, I just want to enjoy it.”
