English Nasal Sounds 

I have a doubt to ask. I struggle pronouncing words and syllables that start and end in the same sound. For eg. Type 1 difficulty Mum, Nun, Rar, bulb, peep etc. Type 2 difficulty Assistance ( A'ssis'tance ) Remember ( Re'mem'ber ) Etc. Type 3 difficulty is. When a word contains letters of N, L, D in the middle or end. I struggle pronouncing the words clearly. I mumble or mispronounce most of the times. Is it because of similiar positioning of tongue for the letters ? I'll be very thankful if someone clears my difficulties and how i should practice to master my pronunciation in difficult words?
