The `Bad Lieutenant` actress - who spent time in rehab in 2008 for an undisclosed condition - thinks it is important for her to always find them time to discuss her problems with a professional, and will even arrange telephone appointments if she can-t make a session in person because of working commitments.
She said: "I love therapy. There is nothing like going into a room and sitting down and talking to someone who has no emotional investment in your life. Having that person who is only committed to helping you be better, I just love it.
"I go once a week and, if not, then every two weeks. And if I`m away I phone in. It`s so necessary, especially in my business."
The 36-year-old star believes it is important to always face her fears and confront difficult situations - even risking drowning because she was so determined to learn to swim.
She told You magazine: "Fight them head on. Just be honest with yourself and face it. That`s everything in life for me. I didn`t know how to swim, so I asked my friend to throw me off a boat. I know it`s crazy, but I did it and I survived."
Eva has been dating filmmaker George Gargurevich for eight years but admits she is still unsure if she wants to marry or have children.
She said: "If I were to get married I`d probably do it in my basement. As for starting a family, I`m honestly not there yet, but who knows? I`m not a planner - so if it happens, it happens. I have seven nephews and nieces and they keep me happy on that front."
