Hi there caldawg89!
I am sorry you are are going through a difficult time right now.
Let's look at positives:
Positives
Gym
You are still going to the gym. YAY!
Can you avoid interacting with the all those women who do nothing but bring such negative energy to the environment?
Can you ignore them and follow a personal routine while there?
Will they talk behind your back? So what……..Some people really suck and there is nothing you can do except avoid them, pretend they don't exist. You don't need them!
Another thing……..could you find a gym buddy who is a decent person and has a similar health and fitness journey to yours?
This is not Gym version of Beverly Hills 90210. Let those superficial women live in their stupid world.
Job
Yes, you can do it!
Go to the training and ROCK IT!
Let them see how dedicated you are. You want this: MAKE IT HAPPEN!!!!!
As for the trip to the big city: look at it as an adventure. Yes, it's scary but it can be fun and memorable. Go see new places do things you can't in your town (museums, gardens, theater, whatever you are into).
Research the city ahead of time: find places to eat where you can stay on track but still have fun or plan on hitting the farmers' market or grocery stores and cook for yourself (if you have access to a kitchen)
You could have 2 weeks of work and fun, all into packed together.
Food Intake
Maybe journaling would help.
I know theory is so much easier than practice. I myself have struggled on and off the wagon for years. I have recently (1 month) found a determination I haven't had before. I visualize myself healthier, feeling and looking better. I am working on it.
Plateaus
They are so frustrating!
Switch your exercise routine a little, alternate between high intensity and lower intensity days. Trick the body out of a learned routine. Also, think about it this way: yep, you are not losing weight right now but your workout regimen helps the body get healthier, your heart works better, your lungs function better, your joints are also benefitting, etc. So, you are helping your body on the inside function better and increase stamina even if the scale is not moving right now.
Rewards
How about you come up with a plan where you reward (NOT food related) yourself for making the good choices you want.
Example: I ate on plan (whatever your plan is) for 2 weeks (no cheating) so I am having a mani, or pedi, or getting a new book, a piece of fashion jewelry, whatever is that you like and want. Increase that for longer time frames and increase the rewards: new shoes, season tickets to theater, etc.
As for sickness and stress: maybe some breathing type of strategies would help, music, yoga type of movements, meditating, dancing and being silly, bubble baths and a good book, etc. Just thinking of some ideas that might help lower stress.
Also, daily vitamins might help increase your immune system and lower sickness incidents.
I wish you the very best and hang in there!
Think how the new training will help you move forward and how happy you will be in the future that you did it!
Keep at it and don't give up!
Best wishes!
