I think that you should wake up every morning and start smiling because you get to go to work that day. I have had a few jobs like that and life was so much better all round.
On the other hand. You do know the field and what it takes to do it every day. But you also know what a difference you can make to someone with just a little effort.
My goal was to get my masters if I decided to go towards politics. I wanted to be a lobbyist for people with developmental disabilities. I wanted to help make laws to help those with disabilities so they can have more rights and they'd be able to live more independently and with less interference from teams and parents and just a lot of people in their business.
If I didn't do that then I wanted to have my masters in, it was called this back in the 80's...., mental retardation. I would have gone to work in the developmental disabilities division of our states DHS and work with those that had been mistreated by institutions and places that were out of business at that time. It was called the Hissom Project and the people who had lived there won a major amount of money in restitution. So the state formed case managers to make sure those person's were being treated correctly and that the money they had won was actually being used for their benefit and not for unscrupulous reasons. One of the clients in the home I worked really wanted to go for rides every evening. He was one of the Hissom clients. The house manager sat down and did the paperwork for him to purchase a vehicle for himself. Of course he would never drive it so it could be said that he didn't need a car, he was retarded and should not have such an extravagant possession.
This is why these case managers were hired. They managed the clients of that court case and made sure they got what they needed.
So this was one of those jobs that would have been right up my alley. I'd have loved to work there and do that work. I worked alongside all these case managers for several years and had great respect for them.
So consider thinking outside the box. Having an MSW does not mean you have to work in one certain field, there are so many that could hire that degree holder. Just because you didn't love your past jobs doesn't mean the next one won't be just what you want.
Please go visit with your grad counselor about what degree and classes to take. They can guide you through the many different options you might have.
