Thank you for the additional information. It helps.
The first step in dealing with what you feel is to find out why you feel this way. You and your therapist might have explored this already but if not, it is very helpful to know where your thoughts come from, why you are so hard on yourself and what leads you to believe that you are not moving ahead in life. Most often, it is something in our childhoods that triggers thoughts about ourselves that bring us down. Abuse, neglect
or other traumas give us the idea that we are not as good as others and that we are alone in life. So by exploring what may have caused what you feel, you can try to challenge those thoughts and feelings.
Second, you may want to work on challenging your beliefs about yourself and others. While other people at work and elsewhere in your life might present as having it all and being very happy, for the most part people only present what they feel makes them look good. So by challenging the belief you have that others are better off than you might help you feel less down about yourself. Write down what you think is true about you and what you feel holds you back from believing good things about yourself. That may help you change those thoughts.
Third, do something everyday to go against what you feel about yourself. For example, if you feel your work makes you unhappy, spend time redoing your resume one day. Focus on what you can improve and see what others say about your resume so you can make it the best you can. Spend another day taking career tests to see what might interest you, etc. Each day make some progress so you have hope of change.
Fourth, try to connect with someone in your life. Pick a person who you have felt some kind of connection to and try to improve that relationship. Or try volunteering your time to others. There is nothing like helping someone to improve your mood and allow you to see that you can make a difference.
Most of all, try not to see yourself as needy and weak. You are much stronger and more intelligent than you give yourself credit for. Just by reaching out today and with your therapist, you show that you have insight and the ability to solve your own problems. Build on that and remind yourself that you are worthy.
I hope this has helped you,
