I wish I could say that PTSD never affects one's job performance, but I am living proof that it can. Fortunately I am retired with a pension as of a year ago, but the stress, fear, bad feelings, depression, anger, etc. that I went through in life were replicated at my job. Jobs are weird things anyway; we're forced to spend a great deal of time with people we may or may not like spending time with. It is of course totally up to you what you decide, but it's great that you have a plan B. I'm guessing you'd make a great therapist given your own experience with these kinds of issues. May God bless your day.

Interesting you mention what you'd like to do in your next job. PTSD interfered with my old job teaching literature, but when I went back to grad school and got retrained, my own experience in PTSD recovery now is an asset in my job teaching psyc classes to nursing students.. Sounds like that before and after story may be in store for you, too.

Sounds like you already know what you want to do, leave your present job and pursue a career as a therapist which would be much more rewarding than pushing supplements. Any transition takes time, so think it over and start to make plans to transition out of our present job, don't break any fences there, or even keep that as a part time job, if you can while you settle back into therapy. In any event, all the best to you what ever you decide :)

Thank you all for your responses. More and more, I'm feeling like I'd do much better work in a less sales-y environment. I'm keeping my current job for now but am applying to be a warm line counselor--dipping my toes into the world of providing counseling and therapy. I've always felt a yearning to really help people, and digging under the surface. While I *am* helping people in personal training, I feel like I'm not *really* helping them in terms of lifestyle changes because there's only so much I can do as a trainer.

For example, there's a woman who had trouble losing weight despite supposedly eating very few calories a day, and since metabolisms cannot defy physical laws, she was definitely eating more than what she told me. A person who has a healthy relationship to food doesn't restrict their food intake to drastic extremes or hide what they actually eat. I wondered if she, too, had disordered eating or an eating disorder, and might do better to see a therapist instead of a trainer. It made me sad to think that I could only do so much to help.

I know that doing these add on's can be tricky, especially if you are not sure of your position on them. But that being said ...and being a natural Sales person...
Develop a stress relieving routine, stretches, Heart strengthening and core building incorporating QI Gong or a similar discipline....this can include breathing structures in them. Then ask current clients to invite a friend they may have that could use some tips. You may gain 1/3 of those as clients. Just remember to ask for appointment dates for individual time at the end of each duo
session.
The other thing is the nutrients. I know you may have problems with this because of what you stated. But every system in our body needs good building block, since our cell structure breakdown and replace in as short a time as two weeks.
Here is an article to help define what are needed. Then look at your options where you work and find a favorite that meets those needs.
Incorporate the language during your sessions. " use those B vitamins and balance what you are using"
Years ago I took a nutrition class, then also the number of breaks I have had...A,B's Calcium collagen builders, Vit C (juices)D's and E's (fish, olive,almond oils) are all necessary to maintain current cell structure and produce new cells. Add in the minerals.
Think of it as helping them taking the next step in getting the most out of your sessions.Don't feel bad about offering this step, most will feel the difference. Just chart it when they buy., remind them when they may do for refills... "How are you doing on your supplements?"

As for the training for your future plan in therapy, get your ducks in a row and apply for grants and any work assisted programs you can get. Nutrition may be covered their, but it is also very important in mental health. Low Vitamin D shows as increased depression. Also stress burns a lot of Vit. C (18 oranges worth) which our bodies do not store, so that has to be taken in regularly. A's for cramping...bone and muscle. Fast food is not nutritional, so if they can't cook the products are even more important.

Then check out programs that do what you want to do nearby, get your foot in the door even as a part time associate ( since they may also cover classes). Find out what they require that you have to get to do the job. Community colleges will normally be cheaper. Then take your classes in the evening or online.

Hugs of support. Take your vitamins too....Brain work takes a lot even if you are reading.
