You are not a failure! You have been involved in higher education for five long years, and even though you don’t have a degree to show for it yet, you have probably learned more though it than a lot of people with diplomas.
Give yourself some time. The job, finances, and schooling issues aren’t anything that can be solved in one day. Take some time for YOU. Try to express to you Fiance how you’re feeling by applying it to his situation or job, that helps with us sometimes when we’re not seeing eye to eye. You are not a failure! Some of the most successful people in this world spent much of their lives getting fired from jobs or rejected by schools or publishers. Some of the world’s most successful authors had to hunt for years for people to publish their books (including JK Rowling–author of the Harry Potter series!) because people just kept rejecting their work.
Think of how much you HAVE accomplished thus far in your life. You’re getting married to a great guy, and you have five years of college under your belt, along with I’m sure many other wonderful things. These bumps in the road DO NOT mean that your intellect, social abilities, or whatever are less than other people’s.
In fact, I think it’s a great sign that you’ve switched majors so many times (as a lot of people have!). It means you’re not going to settle for one thing that you’re not enthusiastic about, you’re chasing your passions, and that in the long term may or may not lead to more money, but definitely more satisfaction out of your life’s work.
If school isn’t an option for right now, it might be a great time to explore other things that you’re interested in that only require certain certifications or just a great personality and work ethic. There are tons of things within health care (nurse’s aids, rehabilitation assistants, etc) that pay really well and don’t require any fancy degrees.
I’ve definitely experienced my own slumps, and can definitely relate to feeling like a failure, especially amidst other people who seem to have it all together! But I started volunteering with organizations that seemed lovely to me, a kids bereavement support group and a women’s crisis pregnancy center, and that helped me figure out where I wanted to go next.
Who knows, maybe this “slump” in the educational career will turn out to be a new opportunity to find something that really suits you. Good luck with everything dear, take time for yourself, and remember that you are infinately valuable as a human being, a loving fiance, and a hard worker!
