Hello everyone 
Thank you all for your posts, and thank you for not telling me that I am being stupid/ungrateful 
I am so lucky. I know I am. But, God, I am so tired. Have never been so tired.
Wrt ds2 indigo is right, I dont post the good stuff about him, I dont post about how polite he is, how loving, how sweet and funny, how is loves to dance to lady gaga, how he is very creative and likes to bake cakes 
I think I am always "on the lookout" for problems IYSWIM? He was late to talk - like ds1. He has speech immaturity - like ds1. He struggles to detach from me atm - like ds1.
I dont think I can do it all again...the appts, the idiots, the ignorance, the money, the stress....I WILL obviously, I would do ANYTHING for my kids, but it is making me feel sick thinking about it 
He is due to start pre school on 16th...it will be horrendous. I am dreading it. What do I do if they start to red flag stuff? Its like I know that this is (or could be) the start of it all again....
I am being an idiot. I am borrowing trouble ahead of time I know, but I cant help it. I have done the whole "they are the experts they know what they are doing" thing and assuming that they have my dc's best interests at heart...I know better now
and I know all of you do too 
I feel like a complete failure...my dsis (I know, I know, you shouldnt compare!!!) has a husband who is well...useless...never there, doesnt do anything with the kids when he is, never did any groups, baby groups etc with her dc, put them in nursery very young even though she is a sahm, spent all her time with them either cleaning or at the shops, never baked/did craft with them, never takes them anywhere (her MIL taught them to swim and ride a bike) AND YET her dc are fine...no academic issues, no sleep issues, no anxiety issues....I feel like such a fool
I did everything "right" - I did the whole baby group thing, took him to parks, soft play, baked, did crafts, dh is a very hands on father, takes him on trips etc...and ds1 struggles so much and always has.
I fell for the whole thing..."if you do this you are a good mum and your child will thrive". Yeah. Right.
My mum thinks its my fault ds1 is like he is - partially because when he slept as a baby (very rare occurance tbh!!) I tried to be as quiet as possible, turned the phone off etc.....apparently this made ds1 "nervous" 
Sigh. I dont know how to stop feeling like this.
Help.
