Difficulty in waking up for fajr salaah and anger management

Q: For a long time I did not follow much of Islam, in fact, very little. I made a very major sin last year @ the age of 34 and that was my turning point. I had gone from praying one salaat every now and then and if I did two on the same day that was an improvement for me. Since my major sin, I'm praying four salaats a day. I tried five, but I think I was praying too much too quickly. So, I dropped back from five to four. Once I'm able to do my salaats with ease I will add the final salaat which is my Fajr prayer that I find most difficult. Since then I have tried to lead a better life and hope to return to Allah Ta'ala in the best of conditions Inshallah.

My question is that the more salaats I am praying, the more angrier I am getting. I am very quick now to overact and my anger escalates very quickly and I know for a fact that this is not me... the less I followed of Islam I never ever used to get this angry... Infact I would always practice being calm in all situations. The regular anger that I feel now would only happen back then when I was pushed to the limit. I don't know what to do. Please explain to me what is happening and what I can do about it. 

Taking care of one's sister in Madinah Munawwarah without performing Umrah

Q: I came to Madinah to my sister who went through a big hardship. She is emotionally in need of me, she can look after herself now physically after recovering Alhumdillah. I did not come with the intention of performing umrah and wish to spend all available time to help my sister (I believe this is also ibaadat).

Will it be a sin on me if I do not perform umrah before leaving? I have never visited Makkah before. I am mentally extremely worried for my sister. I had always wished and prayed for visiting the Ka'aba but I don't want it to be a half-hearted visit.

Taking one's mother and sister on family outings

Q: I am currently living with my parents with my husband and 2 toddlers, my sister lives in her own house but has no kids. Do I need to offer my mother and sister whenever I go out with my husband and children like to the beach or for outings? My father does not take my mother out much and her only opportunity to go out for entertainment is with us. Sometimes I feel guilty if I don't offer them as I would not want to be in their situation one day but I like spending quality time with my husband and children only.
