Am I really sick????????

[slm_nzml]

I am highly sensitive person. recently I broke up. this was my 1st love. I know i should not try again and again to get her back. I should leave her alone . But instead I am not. being HSP my mood swings violently. Sometimes i feel I am so alone. I don't have anyone. I feel I am the one who has more pains than anybody else on this earth. I used to tell my girl about my dreams,expectations,hopes. I was and still feeling that I have so much to say. But when its time for saying I couldn't and still cant express my feelings. I have very very low self esteem. I try to control my anger cause I know my anger. When I am really angry,mad or emotionally hurt I physically hurt myself. People also told me that I am attention seeker, self centered, selfish. But trust me I struggled my life. on my early life when I couldn't afford to buy good I used to drink water days after days, I used to walk 5 kilometers to go to school to save some money.Never ever asked for food or ride from anyone. People told me that I dont understand how other people feels, I always put my needs and wants before them, I always think negative, I always victimize myself.am I really sick? Should I see doctor? Thanks
