How to make friends when introvert & financially poor?

I'm really struggling emotional & physical connection wise, as in meeting those needs.

When I'm not drained from my job that is mostly talking to people I'm at home either resting or trying to get as much done just to survive which leaves so little room for developing relationships. Even when I have energy and time and do go out, I can't afford classes, hobbies, etc. to meet others similar to me. This limits opportunities tremendously plus it's hot af outside where I live. Also, I'm in a rural area. If I 'mess up' interactions or friendships, small towns have a way of getting much smaller much quicker. It just sucks.

When I'm at my job, I always feel bad when I struggle with the balance of getting intentional social interaction vs seeming judged to others by having stronger boundaries around socializing than others(extroverts). Not to mention our world is built for extroverts & how we 'network' so I just feel hopeless sometimes.

Then, when I get the golden opportunity where others initiate hanging out/get to know me & I genuinely want to, it's hard to communicate to others how low-energy I am and may not have capacity to sustain a relationship, i.e. can start but can't continue hanging feels like I'm dodgey/not serious, and idk how to navigate telling folks without hurting them, seeming non-commital, and totally insecure/incapable of friendships.

Anyone else struggle with this?
