No pill can turn off feelings, sometimes meds can help you manage them but it sounds like to me you have more of an issue with shyness, sensitivity and low self esteem. Try to get some therapy and practise self compassion. The more you tell yourself you are no good the more likely you will feel depressed and you will isolate yourself further. Say to yourself 'I'm not boring or crappy I am just a little shy and sensitive'. Maybe read the book 'The highly sensitive person'
