Welcome!!
I hear you on the long days and trying to fit in exercise and good eating.
I tried making my own reasons to my nutritionist about why I couldn't fit in good habits and she helped me figure out a new game plan. If I couldn't exercise for 45 mins at a time, could I do 10-15 mins a few times a day? Of course I could! Once I put it in that mindset, it was "easy" (exercise is never easy, is it?!). Then for eating, buying a food scale was essential to my portion control. I can have all the fruits and veggies I want but planning out the protein was so hard (what 4oz of meat is in my head vs. what it is on the scale was a huge difference!). Making big batches of food and then putting them in portion controlled containers was essential in helping me get the weight off. Also, making sure that the star of my meals is fruits and veggies with a "side" of meat and starch almost instantly changed my life. I also do at least 64oz of calorie free drinks a day (usually flavored seltzer) to make sure I'm well hydrated and full.
In regards to 3fc, I joined a few groups where I felt comfortable chatting and also joined a couple of challenges to post and "compete" with others while we all cheered each other on. This forum made my weight loss journey fun (or as fun as it could be!).
I hope this helps, good luck!
