Yeah I'm 30, nearly 31 into my second term of college. I feel this exact same way. But also I'm super fucking proud of myself for finally taking the initiative to better myself and find a career I love as a disabled human being. I have so many fears and anxieties about what's to come after I graduate because I am entering a pretty competitive field. But I've made it this far and I'm absolutely acing my courses. That's definitely worth something :)
