You are mentally and emotionally stronger than you think. Change isn't for the weak at heart. Interestingly, it takes more heart to change than it does to continue life as is.
I'm not denying that it's hard to change. Nor am I suggesting that you ignore the negative feelings/emotions that will come concerning your change during your time of change. Feelings of:
-- "Is it worth fighting/struggling against those that feel they know what's best for me?"
-- "I'm tired [physically and emotionally drained] of struggling against others. Maybe I should end this changing process and return to my life of 'normalcy'."
-- "Am I crazy for wanting to change?"
I've found that the responses towards these feelings are yes, no, and no.
Yes, it is worth the struggle to go against what others think is best for you, because most of their desires for your life are based on their perceptions of you. Also, some of their desires are based on how they would handle things in your situation. Therein lies the problem: that person is not you and you are not that person. On a continual basis, you cannot have their thoughts or reactions because you do not live in their body--and they do not live in yours. Besides, it is hard trying to live your life based on others' expectations for you if those expecatations run counter to or run beneath the expectations you have for yourself.
No, you should not go back to your life of "normalcy". Granted, interacting with those around you was easier, so was getting things done day to day, but were you satisfied as an individual? There is more satisfaction in changing into the person you've wanted to be compared to being the person who was living just to get along or living just to get by.
No, you are not crazy for wanting to change. Jeremiah 29:11 in the Good News Bible translation states
"I alone know the plans I have for you, plans to bring you prosperity and not disaster, plans to bring about the future you hope for."
God has a plan for each of our lives, whether we believe in Him or not. In other words, if you are not living the life you're meant to live, there will be a nagging desire, suspicion, or restlessness in you that there is something else in your life you should be doing. Therefore, no, you are not crazy for wanting to change.
Change isn't for the weak. Yet, the fact that you're on your path to change (or that you are taking the initial steps to change) proves that you are stronger than you think.
