How to be real? Everyone tells me to be myself when around girls but I don't know how
Hi
I am a 28 years old person, male, overweight and underconfident. I have never dated anyone, in fact my female interaction have been almost zero (apart from work and any other important stuff). Basically I have never been friends with a girl before, never had friends who are girls or never had a girl to even go out with me. I am very insecure about it. I am not an incel, I am not blaming anyone but myself for this situation. I have always embarrassed myself in whatever little conversation I have had with girls. Like really horrible exp. I would not wish it on my worst enemy. But I want to change that I want to be better and be able to talk to people of opposite gender. I don't want to be a player, just a normal person, a person who have friends who are girls.
Everybody tells me to be myself, and that I act differently when I am around girls. I stop being myself and act weirdly when I interact with a girl. They're right. I do act differently when talking to a girl because I don't know how. I get nervous and I think that I should not say or do something that she might not like. That is the problem. I also have some mental health issues which I would not like to discuss here, but I am capable of going around my day like a normal person would. then why not in this department of my life. I simply do not know what to say or do, how to stand and even what should I do with my hands? Its easy for people to say that be yourself. Brother, I don't know how? I don't even know what my real self is? I just want to be normal, please help.
