Suggestions please

Any advice, words of wisdom, experiences or philosophies/philosophers that might make me want to keep going?

The rundown:

I'm turning 27 at the end of the month & I feel like I've wasted my life. The last few years I've been in and out of a mental health hospital - haven't worked or studied for years. I'm moving back in with my parents in about a month. I keep feeling intense panic that it's too late to start again, and very pessimistic about life in general. Thinking about going to uni for something creative even though I know it probably won't help me get a job, I just want to have the energy and will to be passionate about something again - but I'm experiencing a lot of fear and doubt about my ability to pretend to be okay & function / being both older and less talented than everyone there. Life and the future seem very bleak and im struggling to find meaning. How do you all cope?
