Identity crisis: You might find yourself questioning who you are. You have been doing the job for so long that now it seems to be a pertinent part of who you are. Leaving the job would feel like creating a huge gap in your personality, which would seem like a daunting task to fill. 

Fear of failure: Embarking on a new huge adventure will always be accompanied by doubts and a fear of failure. This embarkation into an unexplored territory can seem demanding as well. 

Financial concerns: Combined with all the reasons given above, on this adventure, you also let go of a stable income while your expenses remained the same. This would play a huge role in the pressure one feels while making the decision to change careers and while they go through the process of transition. 

Stress and anxiety due to the unknown, the financial instability, and the new role.

Self-doubt and imposter syndrome: you may question your skills and how deserving you are of the job in question when you are unemployed and/or facing rejection. 

Grief and loss: This may be because of losing your old job or leaving it. It also means leaving work colleagues and an environment where you start to find comfort. 

Self-awareness and mindfulness: it is very helpful to be aware of how you are feeling and not bundle it up and hide it. Staying stoic is helpful, but that doesn't mean you ignore your feelings. While it seems that this is a stage where one should only focus on the future, being mindful is very important. This is because it is what you do in the present that shapes how your future is. If you keep focusing on the future, you might miss out on opportunities in front of you.

Goal setting and planning: Career change as a whole is such a huge task. This David and Goliath situation can cause a lot of stress. An easy way to track your way through this is by breaking down your main goal into small tasks. Planning your path, defining the tasks in a very detailed manner and setting comfortable and plausible deadlines would make a career change seem a little easier and manageable. 

Building resilience: career change is not something that can happen in the blink of an eye. It is a long, tough and sometimes painful ordeal which needs resilience. This is not only because you may need to bear rejection, but also so that you never give up and keep going towards the goal you have set. It also requires sacrifices. Hence, building resilience would be very beneficial for one's mental health as the change careers and life in general

Maintaining work-life balance: A career change does not mean that you leave everything else that you did in your life. It should not become your sole focus in life, only one that you pay more attention to. You should continue to enjoy life with the help of friends, families and hobbies—maybe a little less than before, but it is still important. In some cases, you might as well take a well-deserved break so that your burnout does not carry over into your new job. Try to take this time in life to work out a balance so that you do not burn out or avoid things that make you happy when you start to work again. 

Seeking professional support: All these tips seem easy to use, but when it comes to applications, a helping hand is always appreciated. This helping hand can come in the form of therapy.
