Hello friend.
The fact that your father re married maybe ruined your childish mind (excuse my English)
that fact took your self confidence and you felt unlovable. This is very usual and natural.
but you grow.. and your self confidence doesn’t depends on your father’s choices.
Give and take love with your family..and you will feel more secure.
Maybe you have been closed to yourself as a child or a person.. but you must know that every time you help someone and give him love, you take back love also.
Your self confidence is that something you must change because this is for your self and you deserve good thoughts and opinions about you.love will come anyways.
You can build self confidence by doing good things for yourself
for example exercising everyday for your health
Wearing clothes that makes you feel confident and relaxed and comfortable.
Saying things in your mind that treats you good.
I’m a good person and I deserve good things
I don’t want to be punished by anyone I want to be happy.
I don’t want the relationship that makes me sad. if it makes me sad I would get out of this.
