Is this a MLC?

Deep sense of longing for more and I don’t know why . I have everything I need though. I’m 49 and my kids are grown, 20 and 23 and doing well . I’m becoming a grandpa to a little girl in just found out . All is good. I love my job but it’s a lot. Recovering alcoholic- 5 yrs AF. I’ve switched addictions from Alcohol to fitness . I became a certified weight loss coach. I went from 360 pounds with cirrhosis and morbidly high blood pressure to 200 pounds and an excellent physical health minus some extra skin from weight loss. I have a beautiful loving wife . We have a strong bond and we have no marital issues except for she’s super stubborn and I am too . Lost both parents in 2023 , 3 months apart.
Just some facts before my question; Why do I feel like I have missed the boat with something? Why are my emotions so controlling now? I seem to have 5 great days , then 2 depressed days . I feel like I should be a much better position in my life and I should be. I drowned in the bottle from the time I was 20 until I was 43 so I definitely made some poor choices, but i promised myself I wouldn’t dwell on it, and I really don’t. I’m proud of that . You can ask anybody about me and they’ll tell you Tim is great. He’s hilarious. He is such a good guy. I always put everyone else first. I’m the least selfish person in the world and sometimes I wish I wasn’t. It seems the past year since I’ve gotten older. My brain seems a lot more scattered and uncertain and emotional roller coasters. I have a therapist. I am going to see for the first time in my life the first week in February. I’m going to try because I’ve personally know two people that have said it change their lives so I’m giving it a go. Thanks for listening. I have a tendency to be long-winded.😂🙏 thanks guys for listening and let me know what you think and let me know if there’s any more of you out there that feel the same way. I don’t necessarily think it’s a midlife crisis. I just think I need to meditate more.
