It can take some time grieve for an eleven year relationship, and the grief can become complicated if there were co dependency issues. For eleven years, because of the co dependency, your identity was defined by this person, and by your role in the relationship, and as a result, any sense of identity you had would be diminished, compromised and confused. I am guessing that you were quite young when the relationship began, which would have been be a time in your life when a real sense of who you are would be vague anyway.
Establishing a sense of identity can be confusing anyway, and sometimes it can even be emotionally painful, even for a non dependent person, as issues from childhood are touched upon. Perhaps, in therapy, it might help if you could revisit the issues that happened at the time you met your ex, and the issues in your past that happened prior to meeting him. This will help to give you a sense of who you felt yourself to be at the time of meeting him. This might take some time, as the issues are brought up and dealt with, but in time you will make discoveries about yourself, who you were then. It might also be painful as things are unearthed, but your therapist should ensure that you are safe.
The journey to self discovery can also be very rewarding, and actually rather beautiful. It can be almost like a gift, and it is a beautiful journey that continues after therapy has finished, and lasts a life time. People evolve and change, and their sense of who they are adapts to the evolution. It is never too late to discover who you are, and there are many people who have no idea who they are. You have the opportunity to discover yourself, and therefore are fortunate.
I can imagine that for a long time in the relationship, you used the words "we" and "us", I can imagine that when you look back at the relationship you still use the word "we". Can you look back at the relationship and practice using the words "I" and "he" instead of "we"? Do you think that if you could practice doing this your focus might change, and you can begin to remember how YOU felt, how things affected YOU, what YOUR thoughts were etc? This might help you to gain awareness of yourSELF in the relationship.
Breaking up left me feeling like I lacked purpose - I put so much of my energy into trying to take care of my partner (who was an untreated Adult Child of Alcoholics) that I seldom focused on caring for myself. I've gotten a lot better since then, but I still find it hard to be motivated at work. I felt like my purpose for going to work was to provide for me and my partner as a couple, for the good of our relationship. Now that my work only supports me, I feel like I don't have a reason to work.
In order to break away from the co dependency, you need to discover who you are, as I said above. Discovering who you are begins with looking after YOURSELF. Looking after yourself doesn't just include taking care of your emotional health. It means looking after yourself holistically. It means doing the best for yourself, physically, emotionally, sexually, spiritually, and mentally. Just as you did these things for your partner, making him your priority, now it is time to do them for YOU. Be the friend to yourself that you truly need. Neglecting yourself in any of these areas would be abusive, and you need to turn this around, and begin to treat yourself with true love, true friendship, and true kindness. If you can make an effort every day, to make yourself your first priority in a small way, in time you should notice a shift in your attitude. Working for YOURSELF is a good reason. If you work for YOURSEFLF, you are working to feed your body, the body that you look after. If you work for YOURSELF, you are working to shelter your body, the body you look after. If you work for YOURSELF, you are working to clothe your body, the body you look after etc etc. Can you see that by taking care of all your needs, emotional, physical and mental etc, you are looking after yourself, and by looking after yourself, you are acknowledging your existence - not as someone whose sole purpose is to drown herself for another - but as someone who deserves it, by virtue of the fact that she exists and lives. Life isn't a rehearsal. You can choose to embrace it, and all that it has to offer, the good and the not so good. It really is a gift.
I'm not sure what to do about it. My job is kind of average, but I feel like I'm good at it (under normal circumstances) and it's a good fit for my skills. I take pride in doing a good job, and so I've been feeling guilty about being unmotivated because it has caused me to be unproductive. But most days, I go in and I feel like it's a huge effort just to make myself accomplish something. Has anyone ever experienced something similar to this? How do I get my motivation back?
As your attitude towards yourself shifts, so too should your motivation. Depression can also cause a lack of motivation. Please see your doctor to rule this out, and accept any treatment or help for the depression. By treating the depression, if you have it, you are also looking after yourself in the way I described above.
Please let us know how you get on.
