I am 35 weeks pregnant and feeling blue?

First off, I want to say how happy I am with my boyfriend, and I cant wait to have his baby. He couldnt be more happy either. But I have had to much time to think latly. Like how i am 24 and have no girlfriends, I sit on facebook and see all these girls out with their friends, and I have never had that. Ever. I moved out of moms house as soon as I was 18 and have been working since, had bfs since and never had friends. I feel i am missing out. I tried finding friends online, but i am the only one to stay in touch, they never make an attempt, heres the other thing. I really truly am happy on the inside. Do you think its maybe jealousy? Also I feel i critisize myself, because I dont wear a ton of make up at all and I dont really dress fashioably, just what ever I like. But then when i see these made up girls, every one loves to look at them I for some reason feel bad about myself.but thats expensive to live like that and I always see it as, hmm I will be more healthy in the future, cuz I dont tan, and dont wear alot of make up. I just feel down tonight. I am 35 weeks pregnant, I have bronchitis and I cant do much besides sit on the couch and sit online. HELP
