Thanks - in principal I agree, but it's getting harder and harder to endure my current lifestyle.
I know I've rubbed you up the wrong way previously and may be about to do it again. Apologies in advance.
Not making light of your current situation at all * but I firmly believe that a change in mindset could help.
Taking your commute as an example. It sounds horrendous and stressful. What can you do to change that?
Podcasts, audio books, music are all things that could reduce the misery. A good book might even be something to look forward to!
I presume a bike is out? But every day? Would alternating work? Drive in one day then cycle home and reverse the next day?
Is there anyone to share the journey with? A regular passenger to defray the costs or someone to split the driving with?
Can your start time be varied to better suit the traffic?
Are there any nice places to pull in for a minute and just appreciate the view or that tree?
What about leaving really early and using a gym before work? Or even hitting a gym before going home. Or meeting friends?
There are probably many more things you could try based on what you like and enjoy, or at least prefer to the current situation.
For the bigger picture, it may help to see the current situation (and all the negatives) as a step along the road to the destination of having your own home. Temporary in nature, far from perfect but a necessary point to pass through. Try to focus on the positives - you're saving money for one thing - and what they might mean in the future - a better flat, or one that feels better, at least. Feeling good is not to be overrated.
I get that you've been "at home" for two years but I'd urge you not to look back (that number is only getting bigger) and instead to look forward. You may not know how many days until you have your own place but that number
is getting smaller.
I know that may read as very glib and probably dumb but sometimes it's the small things, done regularly that can have more impact than the big, grand gestures.
* I know a little of what I speak. Older than you, I find myself living in a shared situation that would have been unappealing to me 30 years ago. The other night I had to dig out my Trangia cookset because there wasn't a clean pot in the place (and I was fecked if I was going to wash them - again) just to make dinner.
It's part of a plan, a bigger picture. I keep my spirits up by doing lots of what I've outlined above.
If I were in your shoes I'd be nervous that my dislike of my present circumstances would influence me to make a poor decision with respect to buying a house.
Good luck
