Pregnant and depressed

so i was on birth control when i got pregnant. i was still in high school luckily i graduated with A's. im young im only 18. i cant start college due to my baby. my boyfriend goes out with his friends all the time even when i beg him to stay home with me. i am so alone in my house. i sit and i clean everything once to three times a day. I cry all the time because im stuck in this house. no one wants to hang out with me because im pregnant not even my boyfriend or friends. im so depressed. i am 33 weeks and i wish my little man will come sooner so i can have atleast somebody. i feel alone and helpless. i dont know what im doing im scared. i feel like i am going to do this all alone and im terrified.
