A time will come when you are able to deal with your family effectively. Set and hold your boundaries without guilt. Guilt is always projected on to us and has no place in your process of taking good care of yourself. Your healing is a process and process takes time. If you do, you may find yourself going back to heal the same old issues that got rushed over again.
Deep healing takes time and commitment.
Keep reminding yourself that there is an end to the process. Remember that even though the healing process may feel difficult, you should also expect to feel a certain amount of progress and good feeling about the work you are doing. In a similar way to when you quit drinking or using, the process was hard, but you knew you were on the right track and doing something wonderful for yourself. If you find you are not feeling progress in therapy, talk it over with your therapist and find out why. There is no need to be in endless pain.
