Is finishing college worth it?

25M, snailing my way through college. Tried to do it several years ago, depression/substance abuse got the better of me and I began failing classes so I dropped out. Got a kitchen utility/serving job to save up money and help sustain myself, currently still living with parents.

At 23 I began going back to school and have been doing very well in classes and I’ve been figuring out what major I should do, after considering it I landed on Mass Communication (Advertising or public relations route but unsure yet). I’ve been enjoying the classes and I’m hopeful about this career path.

Now I keep getting a hot/cold response from my mother about what I’m doing now, sometimes she’s very motivational and tells me to keep up my good work and it will all pay off. Other times, like tonight, she says she has no sympathy for me, it’s all my fault that I’m behind in life and that it may or may not be worth it to even go to college, I’ll still wind up doing the job I have now and nothing will change.

I do not want to wash dishes and serve food for a meager wage the rest of my life, I am good enough to finish college, I have the drive and grades now to prove it. My question for everyone who has read this and has a job in a similar field (Advertising/PR), is it worth it for me to complete this track? Are these fields growing or over saturated?
