Emotional and very sensitive. Etc.

It appears that you are going through a early 'mid-life-crisis'. You have lost interest in activities and people, you feel more distracted and anxious about the future. You feel worthless and hopeless. Most of the symptoms that you described indicated a depressive episode. Having certain negative thoughts are normal, but if it impairs your functioning then it needs to be addressed. It seems you are preoccupied, ruminate and overthink about your situation. It is not uncommon for people at a certain age to feel stuck. It will help you cope with the situation better. Life is a continuous flux and we keep reinventing ourselves every moment. It is always better to take two steps forward and one step back rather than get stuck, feel stagnated and not move at all. It is advised that you share this with someone you trust, maybe a friend or a relative.

Consult a clinical psychologist to get a detailed evaluation done to work on the problem from the root cause.
