Feeling lonely

Anyone else feeling lonely in the early stages of pregnancy? I'm only 5 weeks 4 days and don't want to tell friends or family til I'm 12 weeks so I only have my boyfriend to talk to but he just doesn't seem to even begin to understand. I know it's harder for a man cos it's not happening to them but I'm feeling really lonely as I spend my days really tired and struggling to eat due to feeling sick a lot! I feel like he thinks I'm putting it on a little and it can't be that bad, he just doesn't understand. I don't want to make him out to be a rubbish boyfriend cos he's far from that, I just wish he appreciated how I'm feeling a bit more.
