You do sound depressed, so firstly go and chat to you GP about that as ADs/talking to someone should help. Coping with a high energy/demanding toddler would be a nightmare for anyone with depression.
On the advice front I would say be consistent with him or the behaviour is only going to get worse. I know it is hard but you need to remember that you are the parent here and he is just a baby still, he needs your help in understanding his feelings and shouting and timeout will not help in the long run.
Try to make sure he gets lots of undivided attention (i am not pointing fingers, but we are all bad these days for multi-tasking with a laptop or phone, or having the TV on - my toddler will be good as gold but as soon as I talk to daddy when he gets in the door she knows my attention is elsewhere!), if he wants to go out then make sure you have two or three toddler friendly places to take him, local park (or three try to vary it), sure start, library, indoor softplay etc. Try to have some idea what you are doing each day so the week doesn't seem so long.
With my eldest I would do gym/class/something in the morning then park/playground in the afternoon (whatever the weather), that kept her happy - there is nothing worse than hanging around the house with a moaning toddler.
Make sure you are up and dressed before him, with a bag packed with snacks etc so once breakfast is done you can go out for an hour or two. Then come home and have lunch, if he is able involve him in lunch, ask him to choose which bread or what filing. Is he old enough to sit at the table, he might prefer that to highchair/booster? If he throws it just remove the plate/food until he is ready to sit nicely, or he might not be hungry.
Don't expect toys, tv etc to entertain him, he is too young (some kids will play on their own but plenty won't). 5 mins (or less) on a jigsaw/colouring is normal at this age. If anything I would say put away half the toys right now and rotate them so they seem new again in a month or two. He might be overwhelmed with too many toys around him.
Also you didn't mention if he naps, some of the bad behaviour/not sleeping could be that he is overtired, also a break in the day is good for both of you, and gives you a bit of time to get the dinner on or even just sit down with a cup of tea and relax for and hour or two. At not yet two you should have another good year of afternoon naps I would say.
Lastly I hope you do not feel I am getting at you, I am just trying to offer some practical advice. I do sympathise and yes looking after toddlers is really really hard (I also have no family support so I know it is tough to never get a break). I hope you can get some help for your anxiety/depression and start to take a bit of control in the situation. I also hope I have given some useful advice. Good luck.
