What is wrong with me?

There is nothing wrong with you. Sometimes our bodies have chemical imbalances that we can not change. The fact that you are trying medications shows that you know there is some kind of imbalance. I have been diagnosed with depression, anxiety, bipolar, and ptsd as well. I no longer take medication because I have found ways to destress a bit. I have found that getting at least 30 minuets of exercise at least 3 times a week helps with the anxiety and depression. I also tried several calming sleep hypnosis apps until I found one that allows me to calm down before bed. Another think you might want to do is keep a journal of when you feel the most anxious or upset because there are usually things in our lives that trigger these attacks. For me it was my abusive alcoholic ex. Possibly the part about liking everyone is because you are currently single and you feel the need to attach to someone. Just take some time to get to know the person before you choose to date them. If all else fails maybe talk to a therapist of some kind. Sometimes a biased opinion helps us understand what is causing these issues. I truly hope this helps because I've been there and I know how helpless it feels.
