It’s really difficult to have to force yourself to do something you don’t like. Many people are not doing the job they want, most of the time due to financial reasons or external pressures. I’m sorry you feel like you didn’t have a choice, and I’m sorry you feel stuck in this situation. Procrastination is quite normal in such circumstances, so I hope you don’t feel guilty about it. You already spent 7 years doing this and you’re really strong.
Concerning your studies, maybe you can try to ask yourself if there are things you can still appreciate in it. I don’t know in which field you’re working, but maybe there are some aspects in it that you enjoy or you find more interesting. If you can, try to make your own researches and nourrish your own curiosity as much as you can. When I got something that was bothering me during my studies, I tried to look after the subject through readings, videos, online articles… Also, if you feel overwhelmed by a pile of things to do, you can try to list them and you can detail them in diferent subtasks. It can help to makes things easier to do, and sometimes the first step is the most difficult. Finally, if you can, try to work with friends or colleagues and have fun doing it! It can be difficult to keep motivation when we do things all by ourselves but others can be of a great support.
Also, even if we spend a lot of time at work or in a specific career, we can still build some healthy habits for ourselves. Like having little breaks during the day, going outside to get some fresh air, sleeping enough or doing something relaxing at the end of the day. You can still try to spend your free time to enjoy different activities. It’s important to have moments dedicated to something totally different. And if it helps you to feel great, then you never waste your time. Some hobbies doesn’t necessarily need to spend money, like exercising, walking, drawing, watching series/movies online, crafting things with natural or second-hand stuff (…). (Just some random ideas). Spending some time in nature can be really helpful too. But more generally, knowing that you can do something else, something different than your studies, can help you to reduce that feeling of being stuck.
