I couldn’t live a typical suburban life either, OP, so I understand the feeling of resentment, frustration and “stuck-ness” you describe.
It’s hard to provide any practical advice without knowing things you probably won’t want to share like your income, relationship status, children etc. I set myself up for the life I wanted probably easier than most could due to being child-free and having a decent income and flexible job (which has been partly hard work/ education but also a lot of luck/ right-time-right-place).
If finances really do prohibit you from saving even for a small place in a more suitable area (that lends itself better to doing the things you want to) that you can call your own, then I agree with another poster that it’s about doing more things that make you feel alive. Eventually you’ll find something that you feel passionate about and that makes you feel like you are living. Not just working with nothing to look forward to but your Friday night Nando’s!
Start a local book club that meets outdoors in good weather (brings cakes and takeaway coffee) and in a nice cafe otherwise.
Where is your closest body of water? Five minutes fully submerged/ swimming/ bobbing around is exhilarating and a flask of coffee afterwards with a nice cake from a bakery (cake features heavily in my ideal activities 
) while looking at the water can feel quite therapeutic. Maybe next time you’ll stay in for ten minutes, or you’ll hire a paddleboard or swim further or whatever.
Where is your closest hill.. or a farther away one? I always feel like achievements like a hill walk with a picnic lunch (or the swim) are a good way to blow away the cobwebs and feel alive.
I live in a small house that used to be a farm outbuilding so I don’t have a garden as such (it’s cobbled and courtyard-y rather than a traditional front and back garden) but I do have a lot of pots and planters and window boxes. It’s fun (to me!) to plan what I might try to grow each year and potter around the various plants.
These might not be your thing.. but maybe some things to try if your living and financial situation really can’t be changed. Good luck finding your best life.. I have no doubt you can do it!
