Hi, I'd like to help you with your question.
There are many things you can do to help yourself. You mentioned that you are taking Lithium which is a commonly used drug for Bipolar. It is very common when you have a disorder such as Bipolar to have difficulty managing your symptoms even when you take medication. Part of the issue is finding the right medication that works and when you are on it, maintaining the right level in your system. When you are on a medication for a period of time, your body can become used to it and it becomes less effective. Medication effectiveness depends very much on the person's body chemistry. So for example, XYZ medication may work great for one person and do nothing or even cause an adverse reaction in another. And if you do find one that helps your symptoms, you need to adjust it in order for your body to react in the same way it did when you first took it.
Motivation is a very difficult symptom of depression. It often keeps people from helping themselves and reaching out to others. But support and self help are vital in helping you overcome depression. Consider support groups, either on line or in person. People who are experiencing the same symptoms as you are can offer invaluable support, ideas and companionship to help you feel better. Also, working on your depression at home can supplement your therapy or other treatment. Here are resources to help you get started:
Also, if you are not in therapy, you may want to consider going. A therapist can help you cope with the symptoms from your diagnosis. They can offer support and guidance. They can also help you monitor your symptoms so in case you notice how you feel, they may notice it and help you address it.
To find a therapist, you can contact your local community mental health center, either through your local city government or the United Way. You can also ask your doctor for a referral, or you can search on line at http://therapists.psychologytoday.com/rms/.
You can also learn about Bipolar on your own. This will help you better understand your symptoms and be able to help yourself cope better. Here are resources to get you started:
I hope this has helped you,
