Need advice

(This will be a long one sorry)

So I fell out with both my sister over a yr ago now and my life has been less stressful because of it. But something has happened that has me all messed up and I don’t know if I should try and make up with my sisters or not.

The reason I fell out with my older sister is I found out she was telling people that I only got pregnant with my 2nd child because I found out she was pregnant but myself and my husband had been trying for 2 yrs before we got pregnant we never told anyone because we did not want the are you pregnant yet every time we seen family. So when my older sister fell pregnant again she started tell everyone she will give it 3weeks and I will be pregnant with my 3rd it’s so fucked up I am sure to some of you it’s not a big deal but to me it is. Trying for our 2nd almost ended our relationship and the stress I went through was horrible. The reason I am thinking about talking to her and trying to fix it is because a family member just lost her sister you only get one life you should make the most of it. But do I want someone so negative in my life again to bring me down. If you made it to the end awesome any advice would be good thank you xx
