Like you said, I could tell you it'll be okay in four months and to just hold out, but I know it's not that easy. Limbo is a stressful place to be, but it is better to be in limbo than to be in reverse. I know the feeling of proving to yourself that your trans, as curiosity of going back to living as a guy fills our minds from time to time. However, I can assure you that despite those feelings now, going back to being a guy only complicates things further, and the feelings never last anyway. Anything you've done to get where you are will become voided, and should you decide to transition again, you'll need to repeat everything, causing even further frustration.
I am feeling the same way you are, as I too am in limbo. My endocrinologist has suspended my HRT, I'm not living full-time and I'm unemployed.
But, we are who we are. We can doubt ourselves one minute, accept ourselves the next - it doesn't make us any less of a
person. Despite the feeling of having two personalities, it doesn't have to be that way. Integrate some of your male feelings into your life to fit positively; they don't need to fade completely and certainly don't all need to be viewed as being negative. For work, dress a bit more androgynous so you're not
completely engulfing yourself in a masculine appearance. And lastly for work, don't attempt to act masculine if you're not, just be yourself.
Attitude is everything and having the strength to pull through these times makes you one hell of a person. It's tough when we fall, making it easier to give up, but nothing is accomplished as you will find yourself just falling deeper and deeper with less and less of a way out. I know it's hard, but
please try and hold it together. If you focus on the time, it'll seem like forever, so I advise to try and clear your mind from counting down the days. You're a lot further along than I am, so I know you've made it through some battles before. Try and occupy your mind with something else for these four months so you're not constantly thinking about it. Before you know it, you'll be right where you want to be
