You're not alone! This is a hard and sometimes scary thing to do. Don't do it alone, look in to "somatic experiencing" therapy. This is a specific method of therapy where a trained therapist helps you to slowly build your threshold for emotion without causing overwhelm. It's genuinely the only therapy that has made me feel like I'm actually becoming a stronger and more capable person.
Please, don’t ignore or internalize your feelings, it doesn’t bode well. Take it from me if nothing else
