OP i have lots of sympathy: my DS was EXACTLY like yours. I found the first year of his life incredibly difficult. And ignore the person up thread who said as long as he eats/sleeps well he cannot be 'difficult'....she cannot have met my DS!
I found the weeks leading up to him crawling (on his belly like a wounded soldier) at 8mo were the absolute PITS. He was always a grizzly, cry-y frustrated baby but the 7-8mo period was another level of grim.
How I coped was: going out the house twice a day, every day, come rain or shine. At that age DS was having 3 naps per day, 45 mins each: 9.30am, 1pm and 4pm, so I would go out as soon as he woke up from his nap at 10.15, come home for lunch and his nap, and then go out again in the afternoon, he would normally catch 40 winks on the way home, and then dinner/bath/bed.
I searched on netmums (eek, sorry MN!) for lists of baby and toddler groups locally. There are loads in church halls which are v cheap or free. Your local Children's centre will run some. There's rhyme time at the library. I live in London and there are 3 libraries near me running rhyme time at different times throughout the week. Sometimes I went to all three! I would go to parks, shopping centres, feed the ducks, meet friends, visit MIL on her day off work, visit other family members. It was like a military operation to plan such bsuy stimulating days to stop DS whingeing. I also totally get what you say about your LO ot being cuddly....i posted on here a few times and lots of women were like, if your baby is crying pick him up. or buy a sling. he didn;t wanna be held. He wanted to be entertained...!
Here's the good bit though: he is now 14mo. He started walking at 12mo and since then it has been like he has had PERSONALITY TRANSPLANT. he is so happy now, and bootles around playing by himself, walks aroun the different baby-proofed rooms of our flat creating a massive mess all day but is generally a happy little soul. I have even spent the afternoon in the house recently! It is like he is a different baby. I think in my heart he has wanted to walk like a big boy since he was about 4 months old!
I also went back to work when he turned a year old, 3 days per week, and I am SO HAPPY to have some adult company and to do something that's in my comfort zone and which I feel I am good at. If we ever have another baby (and honestly, I am not sure we will ever do it again, for fear of another year like we have just had!) i will be going back to work after 6 or 8 months at the most.
Hang in there and don't be worried this is you, or something you're doing wrong. If you havent got a baby like ours, then you can't possibly understand what it's like

ps - i did also develop PND and after talking to the HV was referred for a course of CBT which was helpful. One of the things my counsellor recommended was finding a little time in the week to DO WHAT I ENJOY . It makes a real different to your mood if you can get away from this situaiton with your baby once a week. Is there a council run leisure centre near you with a creche? you can often put a baby in such a creche for an hour whilst you have a swim, cuppa/cake. Wish I had known about this facility when my baby was younger. Ask your mum to have him or a morning a week so you cna re-group. Failing that, tell your DH that you need a morning every weekend to go and do your own thing. It will help.
