How to workout again

Hi Brooke,
I noticed you mentioned that working out is not necessary to lose weight and I agree. However, I do want to work out and be active 3-4 times a week especially because I have Fibromyalgia and Depression and it really helps with that. However, my issue is that I am a yo-yo exerciser. I get really into it and do about 10 hours/week for a month or two and then I fall off for a few months. While I know the benefits of being active, I can not seem to motivate myself.

C-being active is good for my health
T- I should exercise
A-i make up an excuse and don’t exercise

My contributing thought is always ” I’m tired, lazy, seems like a lot of work to get ready, change and go there”

Part of the reason is because my family is really hell bent on me losing weight and they often will negate the exercise I have done and say it’s not active enough so then it makes me mad and I feel like it’s not enough.

Can you please help me with this? I have numerous reasons why I should work out, but right now its “should” and not “want”.
