How do you stop being desperate?

sometimes i get so desperate for a mate that it seems like i =just cant handle it...i try and try but it seems to prove futile...i have a few girls i speak to but i dont think its going anywhere, why cant i get anyone it shoudlnt be like this, im not even ugly or low on self confidence, whats the problem, 20 years old is too old to not even be close to being with anyone, people tell me pray and pray but it dosent make the desperation go away then when i go and try to talk to any girl it seems like theres a barrier and i cant speak to her no matter how hard i try, so i get up and try again the next day its been this way for months, i see a girl any girl to talk to so i can be in a relationship and it seems like i cant get up to her, then when i do the convo goes fine but nonething happens. whats going on...how can i stop being desperate i dont wanna stop going around looking cz i dont belive that it will come wehn i least expect it cz a person has to put in work
