I Don't Want My Marriage To End!

My wife and I have been married for about 2 yrs now and the last 7 months have been really difficult. I lied to her over our finances. She would ask if we were doing ok and I would just tell here that we were to avoid going into any detail. She found out, I wasn't even man enough to come and tell her myself. I struggle with remembering tasks, lying, not taking responsibility for my own actions, always wanting to be what she wants not myself, I have a difficult time communicating as I will play out the entire argument in my head before I respond or just won't respond at all, I have always had a low self image, and i struggle with keeping to a course. This has severely shaken the trust and confidence that my wife has in me. I have been going to a counselor for about 6 months now and still have difficulty dealing with my issues. It was only recently that I remember that I had been diagnosed with mild ADHD when I was younger and I will be bringing that to his attention when I meet with him next time. I very earnestly want any help and guidance that anyone can offer to help me overcome these issues and save my marriage. I have been able to stop for a few months at a time but only fall back into the same habits when I don't stay focused. I Love my wife dearly but she has trouble believing me when I hurt her. I don't want to hurt her anymore.

Please Help
