Not me but someone close to me:

• There is a difference between “ready for therapy” and “ready for change”. Some people will sit in therapy for years but never see much progress because they are so stuck in doing or thinking something that holds them back.
• Your therapist will tell you things that don’t make sense to you. Listen to them anyway. If they tell you something that seems impossible, don’t ignore it, ask how you can do that. If they tell you something that seems useless, try it anyway, then report back if it doesn’t work and be open for an explanation for why it didn’t work.
• Be brutally honest. Your therapist won’t be able to help you unless you tell them exactly how bad your situation is. If you spend 90% of your day in bed and tell your therapist you’re doing okay, they won’t be able to correctly identify what kind of help you need.
• It is completely normal to miss some of your goals. Therapy takes time and nobody will judge you if you take longer than others. Figuring out how much you should push yourself and when you need a break is hard. Either way, don’t be angry at yourself when something doesn’t work out. As long as you tried, you’re fine.
• Most of your problems are in your head. That doesn’t mean they aren’t real. It doesn’t mean they don’t hurt. It doesn’t mean they aren’t difficult to overcome. It just means that the only person who can solve them is you. A therapist can explain how to solve them but they can’t change your thoughts or your habits.
