Hey TickleMe - I hear you. I frequently have days like this where I feel like I just can't bear it. I spend the whole day just counting down to DP coming home so I can't get a break and some adult company. Even that only lasts around 2 hours as then I have to go to bed when DS does. DP is abroad with work this week so I don't even have that just now. Being lonely is a horrible thing - I really had a hard time with this too. I've only lived here for a few years so don't have that many friends and most of those I do have don't have kids. I can't see them much as they work in the day and I can't go anywhere in the evening, or even invite them over due to the early bed time. My family all live abroad. This is definitely not how I envisaged my maternity leave. One thing that worked for me was the meet a mum board on netmums (sorry!!! it's the only thing i used it for - honest!). I met a few mums just for coffee, some of them were nice but we didn't majorly click; but I've met one mum who I get on brilliantly with and she has been a godsend! We see each other quite frequently now, and she knows DS and is always easy going about how he is and what I need to do. I can text when I'm having a nightmare and she listens. She really has made a huge difference. Might it be worth taking a look?
When it comes to going out, well, my Mom came to the UK for a few weeks when DS was born and her mantra was "what's the worst that can happen?". She's right - if we go out in the car and DS starts to cry, well, I'll just have to stop and calm him down. No biggie. If we're out for a walk and he goes nuts, well, I'll just have to turn round and go home - that's ok. I think it's been about managing my expectations. Sometimes, I think, right - I need to get out today, I'll go to the local retail park for a wander. I'll take the sling and the pushchair and judge which he needs. If he needs food, or just calming down, there's lots of places there to stop, or even the car. If it's just not working, I'll just come home. I try not to stress about - if the trip doesn't work out, we'll just try again another day. And sometimes we even end up having a lovely time :-)
There are days when I can't follow my own advice, believe me, especially when DS is having a particularly fussy time and I feel like I desperately want to get out but he's having none of it. Days like that are taken on an hour by hour basis.
Sorry for the big ramble, but I wanted you to know I know how you feel. I'm sure many on this thread do.
