Hi.
It seems that you are having some interpersonal problems. You can discuss it in detail with me or any other Psychiatrist for some help.
It is important to understand a few things.. Are there some repetitive patterns? Are you having problems with only one person or more than one? Does "so much of negativity" mean you are in a difficult or toxic environment?
A mental health professional can discuss in detail and help you.
Next Steps
Consult a Psychiatrist
Health Tips
Start writing a gratitude journal and focus on positive things about you. Negative self-talk can make things worse for you.
As recommended by my colleague here, get MMPI test done.
