I'd like to start by saying that there is no shame in seeking psychological help, it can be a great resource and truthfully most people could benefit from it at some point in their lives. However, I do understand that it isn't for everyone and also that not everyone can afford it. I am fortunate enough to live in Canada where I can access this help for free should I so choose, but I know that not everyone has this option.
Psychological counseling can be extremely helpful because it means that you have a person that you can confide in. You can tell this person anything without worrying about burdening them, or them judging you as you might with friends or family. I have found that journaling is a great alternative to this because it allows you to get everything out and off of your chest without actually having to verbalize it. Journaling doesn't need to be complicated or formal, just grab a notebook and write anything, remember you are the only person that will see it.
Many people feel like their life is spiraling out of control and they can't do anything about it. Sometimes things in life are out of our control, but it may help to take charge of the things that you can control. For instance maybe you can only make the minimum payments on your credit card bill and thus can't get out of debt, that can be hard to change, but you would be surprised at how much of a difference it can make in your mood if you stay organized in the rest of your life. Stay on top of things at work or school, keep your house clean and uncluttered. These things can have a big effect on your psychological and emotional state.
Most people underestimate the power that your physical health has over your mental health. Eating well and staying physically active has been proven to improve your overall mental health as well as your physical health. Plus you can feel better about your physical appearance which is often a big self-esteem boost.
One of the worst things that you can do when you are feeling mentally unwell us to seclude yourself from the outside world. Instead, make a conscious effort to spend time with people who support you and make you happy. However, avoid people who put you down or make you feel bad about yourself.
Just making a conscious effort to organize your life and making positive decisions for yourself can make you feel much better. Take charge of your life and do what you need to in order to stay happy, You're health depends on it.
