drinking alchohol before meeting with a friend in town?

[A]

I have social anxiety and i feel like im losing all my friends and this person is one of my best friends but lately iv even been finding it hard to be around her aswell i am so silent and i dont want to lose another friend, she jas problems tooo and she understands but i dont want her going home being like omg i had the most boring time :/

Im getting the bus down and back, im not getting drunk just enough so i dont care, is it a bad idea, im worried about getting raped or something

Thanks in advance
