My anxiety gets so bad I have digestive problems

This might be a little tmi for some so here’s a little warning. When my anxiety gets bad I have problems going to the bathroom. It’ll be two three weeks sometimes. My cramps were so bad today I took the day off from work to take something to get things moving. I had to explain this to my employer today because they wanted to make sure it’s not COVID. I’m super embarrassed now. I’m scared to even show my face at work tomorrow. I tense up so bad, everything tenses. I’ve gone to the emergency room five times in the past three years about the constipation. I’ll be ok for a bit but then anxiety screws it up. My doctor put me on anxiety meds but those kill any joy I had, made me numb, and I slept all the time. I don’t know what to do anymore. Laxatives make me feel so sick. Fiber helps but not when my anxiety gets bad. I need to relax my body but I can’t focus. My mind won’t chill to let me. I am in therapy and my therapist says it is normal while dealing with trauma. But I want it to stop. I also get severe migraines that make me feel sick, dizzy, and they last days. My doctor has tried giving me different things but those meds sometimes make the migraines worse. I try and not take so much over the counter migraine meds because I know it’s not good for your liver. I’ve also missed work for these because I can’t even walk straight. I’ve gone to the emergency room over them before and they gave me Benadryl. I get muscle spasms everywhere and have had those since elementary school. I’m almost 30 now and they are increasing. Doctor says I’m overall healthy and can never find an issue when I’m examined other than constipation. My mind is sick and making my body sick.
