Welcome to the forum. There are many people who have similar problems like you. There is nothing to panic or get stressed up. Lifestyle today is very fast. Tension, anxiety
and stress are apart of life. Yes, you are suffering from personality disorder
but it is nice that you can understand it and trying to get out of it. There are many who suffer and are not even aware of their problem, finally they get depressed and have complicated problems.
Take care of your diet, eat what makes you feel happy. Exercise regularly and start visiting friends.
Peer pressure is always there, take it casually. Think positively and encourage yourself to socialize as much as you can. Perform meditation
. Keep yourself well hydrated. Recognize your skills and talents and feel proud about it. Do not bother what others say about you. You can also speak out.
Have a good day, take care.
If you find yourself still in a difficult situation please visit a doctor you require some anti-depressants and mood elevators. ( never take over dose of the medicine )
